seven-transmembrane G protein-coupled receptor superfamily; This hierarchical evolutionary model represents the seven-transmembrane (7TM) receptors, often referred to as G protein-coupled receptors (GPCRs), which transmit physiological signals from the outside of the cell to the inside via G proteins. GPCRs constitute the largest known superfamily of transmembrane receptors across the three kingdoms of life that respond to a wide variety of extracellular stimuli including peptides, lipids, neurotransmitters, amino acids, hormones, and sensory stimuli such as light, smell and taste. All GPCRs share a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes. However, some 7TM receptors, such as the type 1 microbial rhodopsins, do not activate G proteins. Based on sequence similarity, GPCRs can be divided into six major classes: class A (the rhodopsin-like family), class B (the Methuselah-like, adhesion and secretin-like receptor family), class C (the metabotropic glutamate receptor family), class D (the fungal mating pheromone receptors), class E (the cAMP receptor family), and class F (the frizzled/smoothened receptor family). Nearly 800 human GPCR genes have been identified and are involved essentially in all major physiological processes. Approximately 40% of clinically marketed drugs mediate their effects through modulation of GPCR function for the treatment of a variety of human diseases including bacterial infections.

mas-related G protein-coupled receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; The Mas-related G-protein coupled receptor (Mrgpr) family constitutes a group of orphan receptors exclusively expressed in nociceptive primary sensory neurons and mast cells in the skin. Members of the Mrgpr family have been implicated in the modulation of nociception, pruritus (itching), and mast cell degranulation. The Mrgpr family in rodents and humans contains more than 50 members that can be grouped into 9 distinct subfamilies: MrgprA, B, C (MrgprX1), D, E, F, G, H (GPR90), and the primate-specific MrgprX subfamily. Some Mrgprs can be activated by endogenous ligands such as beta-alanine, adenine (a cell metabolite and potential transmitter), RF-amide related peptides, or salusin-beta (a bioactive peptide). However, the effects of these agonists are not clearly understood, and the physiological role of the individual receptor family members remains to be determined. Also included in this family is Mas-related G-protein coupled receptor 1-like (MAS1L) which is only found in primates. The angiotensin-II metabolite angiotensin is an endogenous ligand for MAS1L.

Kinetoplastid RNA Editing Protein A2 (KREPA2); The KREPA2 (TbMP63) protein is a component of the parasitic protozoan's KREPA RNA editing catalytic complex (RECC). Kinetoplastid RNA editing (KRE) proteins occur as pairs or sets of related proteins in multiple complexes. KREPA complex is composed of six components (KREPA1-6), which share a conserved C-terminal region containing an oligonucleotide-binding (OB)-fold-like domain. KREPAs are responsible for the site-specific insertion and deletion of U nucleotides in the kinetoplastid mitochondria pre-messenger RNA. Apart from the conserved C-terminal OB-fold domain, KREPA1, KREPA2, and KREPA3 contain two conserved C2H2 zinc-finger domains. KREPA2 and kinetoplastid RNA editing ligase 1 (KREL1) are specific for ligation post-U-deletion and are paralogous to KREL2 and KREPA1 that are specific for ligation post-U-insertion. KREPA2, is critical for RECC stability and KREL1 integration into the complex. Pssm-ID: 467780 [Multi-domain] Cd Length: 424 Bit Score: 41.01 E-value: 1.50e-03

anaphylatoxin receptors and related G protein-coupled chemokine receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; This subfamily of G-protein coupled receptors includes anaphylatoxin receptors, formyl peptide receptors (FPR), prostaglandin D2 receptor 2, GPR1, and related chemokine receptors. The anaphylatoxin receptors are a group of G-protein coupled receptors that bind anaphylatoxins. The members of this group include C3a and C5a receptors. The formyl peptide receptors (FPRs) are chemoattractant GPCRs that involved in mediating immune responses to infection. They are expressed mainly on polymorphonuclear and mononuclear phagocytes and bind N-formyl-methionyl peptides (FMLP), which are derived from the mitochondrial proteins of ruptured host cells or invading pathogens. Chemokine receptor-like 1 (also known as chemerin receptor 23) is a GPCR for the chemoattractant adipokine chemerin, also known as retinoic acid receptor responder protein 2 (RARRES2), and for the omega-3 fatty acid derived molecule resolvin E1. Interaction with chemerin induces activation of the MAPK and PI3K signaling pathways leading to downstream functional effects, such as a decrease in immune responses, stimulation of adipogenesis, and angiogenesis. On the other hand, resolvin E1 negatively regulates the cytokine production in macrophages by reducing the activation of MAPK1/3 and NF-kB pathways. Prostaglandin D2 receptor, also known as CRTH2, is a chemoattractant G-protein coupled receptor expressed on T helper type 2 cells that binds prostaglandin D2 (PGD2). PGD2 functions as a mast cell-derived mediator to trigger asthmatic responses and also causes vasodilation. PGD2 exerts its inflammatory effects by binding to two G-protein coupled receptors, the D-type prostanoid receptor (DP) and PD2R2 (CRTH2). PD2R2 couples to the G protein G(i/o) type which leads to a reduction in intracellular cAMP levels and an increase in intracellular calcium. GPR1 is an orphan receptor that can be activated by the leukocyte chemoattractant chemerin, thereby suggesting that some of the anti-inflammatory actions of chemerin may be mediated through GPR1.

FPRs bind N-formyl peptides, which are derived from the mitochondrial proteins of ruptured host cells or invading pathogens. Activation of FPRs by N-formyl peptides such as N-formyl-Met-Leu-Phe (FMLP) triggers a signaling cascade that stimulates neutrophil accumulation, phagocytosis and superoxide production. These responses are mediated through a pertussis toxin-sensitive G(i) protein that activates a PLC-IP3-calcium signaling pathway. While FPRs are involved in host defense responses to bacterial infection, they can also suppress the immune system under certain conditions.

opioid receptors and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes opioid receptors, somatostatin receptors, melanin-concentrating hormone receptors (MCHRs), and neuropeptides B/W receptors. Together they constitute the opioid receptor-like family, members of the class A G-protein coupled receptors. Opioid receptors are coupled to inhibitory G proteins of the G(i/o) family and are involved in regulating a variety of physiological functions such as pain, addiction, mood, stress, epileptic seizure, and obesity, among many others. G protein-coupled somatostatin receptors (SSTRs), which display strong sequence similarity with opioid receptors, binds somatostatin (somatotropin release inhibiting factor), a polypeptide hormone that regulates a wide variety of physiological functions such as neurotransmission, cell proliferation, contractility of smooth muscle cells, and endocrine signaling as well as inhibition of the release of many secondary hormones. MCHR binds melanin concentrating hormone and is presumably involved in the neuronal regulation of food intake. Despite strong homology with somatostatin receptors, MCHR does not appear to bind somatostatin. Neuropeptides B/W receptors are primarily expressed in the CNS and stimulate the cortisol secretion by activating the adenylate cyclase- and the phospholipase C-dependent signaling pathways.

atypical chemokine receptor 4, member of the class A family of seven-transmembrane G protein-coupled receptors; ACKR4 was first reported to bind several CC chemokines including CCL19, CCL21, and CCL25 and was originally designated CCR11. AKCR4 is unable to couple to G-protein and, instead, it preferentially mediates beta-arrestin dependent processes, such as receptor internalization, after ligand binding. Thus, ACKR4 may act as a scavenger receptor to suppress the effects of proinflammatory chemokines. Unlike the classical chemokine receptors that contain a conserved DRYLAIV motif in the second intracellular loop, which is required for G-protein coupling, the ACKRs lack this conserved motif and fail to couple to G-proteins and induce classical GPCR signaling. Five receptors have been identified for the ACKR family, including CC-chemokine receptors like 1 and 2 (CCRL1 and CCRL2), CXCR7, Duffy antigen receptor for chemokine (DARC), and D6. Both ACKR1 (DARC) and ACKR3 (CXCR7) show low sequence homology to the classic chemokine receptors. Pssm-ID: 320304 [Multi-domain] Cd Length: 276 Bit Score: 67.46 E-value: 2.03e-12

CXC chemokine receptor types 1 and 2, member of the class A family of seven-transmembrane G protein-coupled receptors; CXCR1 and CXCR2 are closely related chemotactic receptors for a group of CXC chemokines distinguished by the presence of the amino acid motif ELR immediately adjacent to their CXC motif. Expression of CXCR1 and CXCR2 is strictly controlled in neutrophils by external stimuli such as lipopolysaccharide (LPS), tumor necrosis factor (TNF)-alpha, Toll-like receptor agonists, and nitric oxide. CXCL8 (formerly known as interleukin-8) binds with high-affinity and activates both receptors. CXCR1 also binds CXCL7 (neutrophil-activating protein-2), whereas CXCR2 non-selectively binds to all seven ELR-positive chemokines (CXCL1-7). Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines.

protease-activated receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; This subfamily includes purinergic receptor P2Y8 and protease-activated receptors. P2Y8 (or P2RY8) expression is often increased in leukemia patients, and it plays a role in the pathogenesis of acute leukemia. P2Y8 is phylogenetically closely related to the protease-activated receptors (PARs), which are activated by serine proteases such as thrombin, trypsin, and tryptase. These proteases cleave the extracellular domain of the receptor to form a new N-terminus, which in turn functions as a tethered ligand. The newly-formed tethered ligand binds intramolecularly to activate the receptor and triggers G-protein binding and intracellular signaling. Four different types of the protease-activated receptors have been identified (PAR1-4) and are predominantly expressed in platelets. PAR1, PAR3, and PAR4 are activated by thrombin, whereas PAR2 is activated by trypsin. The PARs are known to couple with several G-proteins including Gi (cAMP inhibitory), G12/13 (Rho and Ras activation), and Gq (calcium signaling) to activate downstream signaling messengers which induces numerous cellular and physiological effects.

HCARs are members of the class A family of G-protein coupled receptors (GPCRs). HCAR subfamily contain three receptor subtypes: HCAR1, HCAR2, and HCAR3. The endogenous ligand of HCAR1 (also known as lactate receptor 1, GPR104, or GPR81) is L-lactic acid. The endogenous ligands of HCAR2 (also known as niacin receptor 1, GPR109A, nicotinic acid receptor) and HCAR3 (also known as niacin receptor 2, orGPR109B) are 3-hydroxybutyric acid and 3-hydroxyoctanoic acid, respectively.

Angiotensin II (Ang II), the main effector in the renin-angiotensin system, plays a crucial role in the regulation of cardiovascular homeostasis through its type 1 (AT1) and type 2 (AT2) receptors. Ang II contributes to cardiovascular diseases such as hypertension and atherosclerosis via AT1R activation. Ang II increases blood pressure through Gq-mediated activation of phospholipase C, resulting in phosphoinositide (PI) hydrolysis and increased intracellular calcium levels. Through the AT2 receptor, Ang II counteracts the vasoconstrictor action of AT1R and thereby induces vasodilation, sodium excretion, and reduction of blood pressure. Bradykinins (BK) are pro-inflammatory peptides that mediate various vascular and pain responses to tissue injury through its B1 and B2 receptors. Apelin (APJ) receptor binds the endogenous peptide ligands, apelin and Toddler/Elabela. APJ is an adipocyte-derived hormone that is ubiquitously expressed throughout the human body, and Toddler/Elabela is a short secretory peptide that is required for normal cardiac development in zebrafish. Activation of APJ receptor plays key roles in diverse physiological processes including vasoconstriction and vasodilation, cardiac muscle contractility, angiogenesis, and regulation of water balance and food intake.

neuropeptide Y receptors and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; NPY is a 36-amino acid peptide neurotransmitter with a C-terminal tyrosine amide residue that is widely distributed in the brain and the autonomic nervous system of many mammalian species. NPY exerts its functions through five, G-protein coupled receptor subtypes including NPY1R, NPY2R, NPY4R, NPY5R, and NPY6R; however, NPY6R is not functional in humans. NYP receptors are also activated by its two other family members, peptide YY (PYY) and pancreatic polypeptide (PP). They typically couple to Gi or Go proteins, which leads to a decrease in adenylate cyclase activity, thereby decreasing intracellular cAMP levels, and are involved in diverse physiological roles including appetite regulation, circadian rhythm, and anxiety. Also included in this subgroup is prolactin-releasing peptide (PrRP) receptor (previously known as GPR10), which is activated by its endogenous ligand PrRP, a neuropeptide possessing C-terminal Arg-Phe-amide motif. There are two active isoforms of PrRP in mammals: one consists of 20 amino acid residues (PrRP-20) and the other consists of 31 amino acid residues (PrRP-31). PrRP receptor shows significant sequence homology to the NPY receptors, and a micromolar level of NPY can bind and completely inhibit the PrRP-evoked intracellular calcium response in PrRP receptor-expressing cells, suggesting that the PrRP receptor shares a common ancestor with the NPY receptors.

These receptors share significant sequence homology with each other, suggesting that they have a common evolutionary origin. Vasopressin, also known as arginine vasopressin or anti-diuretic hormone, is a neuropeptide synthesized in the hypothalamus. The actions of vasopressin are mediated by the interaction of this hormone with three tissue-specific subtypes: V1AR, V1BR, and V2R. Although vasopressin differs from oxytocin by only two amino acids, they have divergent physiological functions. Vasopressin is involved in regulating osmotic and cardiovascular homeostasis, whereas oxytocin plays an important role in the uterus during childbirth and in lactation. GnRHR, also known as luteinizing hormone releasing hormone receptor (LHRHR), plays an central role in vertebrate reproductive function; its activation by binding to GnRH leads to the release of follicle stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland. Neuropeptide S (NPS) promotes arousal and anxiolytic-like effects by activating its cognate receptor NPSR. NPSR has also been associated with asthma and allergy.

G protein-coupled receptor 17, member of the class A family of seven-transmembrane G protein-coupled receptors; GPR17 is a Forkhead box protein O1 (FOXO1) target and abundantly expressed in agouti-related peptide (AGRP) neurons. FOXO1 is a transcription factor that plays key roles in regulation of gluconeogenesis and glycogenolysis by insulin signaling. For instance, food intake and body weight increase when hypothalamic FOXO1 is activated, whereas they both decrease when FOXO1 is inhibited. However, a recent study has been reported that GPR17 deficiency in mice did not affect food intake or glucose homeostasis. Thus, GPR17 may not play a role in the control of food intake, body weight, or glycemic control. GPR17 is phylogenetically closely related to purinergic P2Y and cysteinyl-leukotriene receptors.

cysteinyl leukotriene receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Cysteinyl leukotrienes (LTC4, LTD4, and LTE4) are the most potent inflammatory lipid mediators that play an important role in human asthma. They are synthesized in the leucocytes (cells of immune system) from arachidonic acid by the actions of 5-lipoxygenase and induce bronchial constriction through G protein-coupled receptors, CysLTR1 and CysLTR2. Activation of CysLTR1 by LTD4 induces airway smooth muscle contraction and proliferation, eosinophil migration, and damage to the lung tissue. They belong to the class A GPCR superfamily, which all have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

P2Y purinoceptors 6 and 3, and similar proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes P2Y receptor 6 (P2Y6), P2Y3, and P2Y3-like proteins. These receptors belong to the G(i) class of a family of purinergic G-protein coupled receptors. In the CNS, P2Y6 plays a role in microglia activation and phagocytosis, and is involved in the secretion of interleukin from monocytes and macrophages in the immune system. The P2Y receptor family is composed of eight subtypes, which are activated by naturally occurring extracellular nucleotides such as ATP, ADP, UTP, UDP, and UDP-glucose. These eight receptors are ubiquitous in human tissues and can be further classified into two subfamilies based on sequence homology and second messenger coupling: a subfamily of five P2Y1-like receptors (P2Y1, P2Y2, P2Y4, P2Y6, and P2Y11Rs) that are coupled to G(q) protein to activate phospholipase C (PLC) and a second subfamily of three P2Y12-like receptors (P2Y12, P2YR13, and P2Y14Rs) that are coupled to G(i) protein to inhibit adenylate cyclase. Several cloned subtypes, such as P2Y3, P2Y5, and P2Y7-10, are not functional mammalian nucleotide receptors. The native agonists for P2Y receptors are: ATP (P2Y2, P2Y12), ADP (P2Y1, P2Y12, and P2Y13), UTP (P2Y2, P2Y4), UDP (P2Y6, P2Y14), and UDP-glucose (P2Y14).

cholecystokinin receptors and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; This group represents four G-protein coupled receptors that are members of the RFamide receptor family, including cholecystokinin receptors (CCK-AR and CCK-BR), orexin receptors (OXR), neuropeptide FF receptors (NPFFR), and pyroglutamylated RFamide peptide receptor (QRFPR). These RFamide receptors are activated by their endogenous peptide ligands that share a common C-terminal arginine (R) and an amidated phenylanine (F) motif. CCK-AR (type A, alimentary; also known as CCK1R) is found abundantly on pancreatic acinar cells and binds only sulfated CCK-peptides with very high affinity, whereas CCK-BR (type B, brain; also known as CCK2R), the predominant form in the brain and stomach, binds CCK or gastrin and discriminates poorly between sulfated and non-sulfated peptides. CCK is implicated in regulation of digestion, appetite control, and body weight, and is involved in neurogenesis via CCK-AR. There is some evidence to support that CCK and gastrin, via their receptors, are involved in promoting cancer development and progression, acting as growth and invasion factors. Orexins (OXs; also referred to as hypocretins) are neuropeptide hormones that regulate the sleep-wake cycle and potently influence homeostatic systems regulating appetite and feeding behavior or modulating emotional responses such as anxiety or panic. OXs are synthesized as prepro-orexin (PPO) in the hypothalamus and then proteolytically cleaved into two forms of isoforms: orexin-A (OX-A) and orexin-B (OX-B). OXA is a 33 amino-acid peptide with N-terminal pyroglutamyl residue and two intramolecular disulfide bonds, whereas OXB is a 28 amino-acid linear peptide with no disulfide bonds. OX-A binds orexin receptor 1 (OX1R) with high-affinity, but also binds with somewhat low-affinity to OX2R, and signals primarily to Gq coupling, whereas OX-B shows a strong preference for the orexin receptor 2 (OX2R) and signals through Gq or Gi/o coupling. The 26RFa, also known as QRFP (Pyroglutamylated RFamide peptide), is a 26-amino acid residue peptide that exerts similar orexigenic activity including the regulation of feeding behavior in mammals. It is the ligand for G-protein coupled receptor 103 (GPR103), which is predominantly expressed in paraventricular (PVN) and ventromedial (VMH) nuclei of the hypothalamus. GPR103 shares significant protein sequence homology with orexin receptors (OX1R and OX2R), which have recently shown to produce a neuroprotective effect in Alzheimer's disease by forming a functional heterodimer with GPR103. Neuropeptide FF (NPFF) is a mammalian octapeptide that has been implicated in a wide range of physiological functions in the brain including pain sensitivity, insulin release, food intake, memory, blood pressure, and opioid-induced tolerance and hyperalgesia. The effects of NPFF are mediated through neuropeptide FF1 and FF2 receptors (NPFF1-R and NPFF2-R) which are predominantly expressed in the brain. NPFF induces pro-nociceptive effects, mainly through the NPFF1-R, and anti-nociceptive effects, mainly through the NPFF2-R.

G protein-coupled receptors for prostanoids, member of the class A family of seven-transmembrane G protein-coupled receptors; Prostanoids are the cyclooxygenase (COX) metabolites of arachidonic acid, which include the prostaglandins (PGD2, PGE2, PGF2alpha), prostacyclin (PGI2), and thromboxane A2 (TxA2). These five major bioactive prostanoids acts as mediators or modulators in a wide range of physiological and pathophysiological processes within the kidney and play important roles in inflammation, platelet aggregation, and vasoconstriction/relaxation, among many others. They act locally by preferentially interacting with G protein-coupled receptors designated DP, EP. FP, IP, and TP, respectively. The phylogenetic tree suggests that the prostanoid receptors can be grouped into two major branches: G(s)-coupled (DP1, EP2, EP4, and IP) and G(i)- (EP3) or G(q)-coupled (EP1, FP, and TP), forming three clusters.

G protein-coupled receptor 182, member of the class A family of seven-transmembrane G protein-coupled receptors; GPR182 is an orphan G-protein coupled receptor that belongs to the class A of seven-transmembrane GPCR superfamily. When GPR182 gene was first cloned, it was proposed to encode an adrenomedullin receptor. However when the corresponding protein was expressed, it was found not to respond to adrenomedullin (ADM). All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

Activation of CCR10 by its two ligands mediates diverse activities, ranging from leukocyte trafficking to skin cancer. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines. The CC chemokine receptors are all activating the G protein Gi. Pssm-ID: 341332 [Multi-domain] Cd Length: 280 Bit Score: 47.85 E-value: 6.09e-06

Atrophin-1 family; Atrophin-1 is the protein product of the dentatorubral-pallidoluysian atrophy (DRPLA) gene. DRPLA OMIM:125370 is a progressive neurodegenerative disorder. It is caused by the expansion of a CAG repeat in the DRPLA gene on chromosome 12p. This results in an extended polyglutamine region in atrophin-1, that is thought to confer toxicity to the protein, possibly through altering its interactions with other proteins. The expansion of a CAG repeat is also the underlying defect in six other neurodegenerative disorders, including Huntington's disease. One interaction of expanded polyglutamine repeats that is thought to be pathogenic is that with the short glutamine repeat in the transcriptional coactivator CREB binding protein, CBP. This interaction draws CBP away from its usual nuclear location to the expanded polyglutamine repeat protein aggregates that are characteriztic of the polyglutamine neurodegenerative disorders. This interferes with CBP-mediated transcription and causes cytotoxicity. Pssm-ID: 460830 [Multi-domain] Cd Length: 991 Bit Score: 48.61 E-value: 7.50e-06

They are a member of the class A G-protein coupled receptors that bind free fatty acids. The FFAR subfamily is composed of three receptors, each encoded by a separate gene (FFAR1, FFAR2, and FFAR3). These genes and a fourth pseudogene, GPR42, are localized together on chromosome 19. FFAR2 and FFAR3 are cell-surface receptors for short chain FFAs (SCFAs) with different ligand affinities, whereas FFAR1 is a receptor for medium- and long-chain FFAs. FFAR2 activation by SCFA suppresses adipose insulin signaling, which leads to inhibition of fat accumulation in adipose tissue. FAAR3 is expressed in intestinal L cells, which produces glucagon-like peptide 1 (GLP-1) and peptide YY (PYY), thus suggesting that this receptor may be involved in energy homeostasis. FFARs are considered important components of the body's nutrient sensing mechanism, and therefore, these receptors are potential therapeutic targets for the treatment of metabolic disorders, such as type 2 diabetes and obesity.

neuropeptide Y receptor type 1, member of the class A family of seven-transmembrane G protein-coupled receptors; NPY is a 36-amino acid peptide neurotransmitter with a C-terminal tyrosine amide residue that is widely distributed in the brain and the autonomic nervous system of many mammalian species. NPY exerts its functions through five, G-protein coupled receptor subtypes including NPY1R, NPY2R, NPY4R, NPY5R, and NPY6R; however, NPY6R is not functional in humans. NYP receptors are also activated by its two other family members, peptide YY (PYY) and pancreatic polypeptide (PP). They typically couple to G(i) or G(o) proteins, which leads to a decrease in adenylate cyclase activity, thereby decreasing intracellular cAMP levels, and are involved in diverse physiological roles including appetite regulation, circadian rhythm, and anxiety. When NPY signals through NPY2R in concert with NPY5R, it induces angiogenesis and consequently plays an important role in revascularization and wound healing. On the other hand, when NPY acts through NPY1R and NPYR5, it acts as a vascular mitogen, leading to restenosis and atherosclerosis.

Bombesin is a tetradecapeptide, originally isolated from frog skin. Mammalian bombesin-related peptides are widely distributed in the gastrointestinal and central nervous systems. The bombesin family receptors couple mainly to the G proteins of G(q/11) family. NMBR functions as the receptor for the neuropeptide neuromedin B, a potent mitogen and growth factor for normal and cancerous lung and for gastrointestinal epithelial tissues. Gastrin-releasing peptide is an endogenous ligand for GRPR and shares high sequence homology with NMB in the C-terminal region. Both NMB and GRP possess bombesin-like biochemical properties. BRS-3 is classified as an orphan receptor and suggested to play a role in sperm cell division and maturation. BRS-3 interacts with known naturally-occurring bombesin-related peptides with low affinity; however, no endogenous high-affinity ligand to the receptor has been identified. The bombesin receptor family belongs to the seven transmembrane rhodopsin-like G-protein coupled receptors (class A GPCRs), which perceive extracellular signals and transduce them to guanine nucleotide-binding (G) proteins.

CC chemokine receptor type 6, member of the class A family of seven-transmembrane G protein-coupled receptors; CCR6 is the only known receptor identified for the chemokine CCL20 (also known as macrophage inflammatory protein-3alpha, MIP-3alpha). CCR6 is expressed by all mature human B cells, effector memory T-cells, and dendritic cells found in the gut mucosal immune system. CCL20 contributes to recruitment of CCR6-expressing cells to Peyer's patches and isolated lymphoid follicles in the intestine, thereby promoting the assembly and maintenance of organized lymphoid structures. Also, CCL20 expression is highly inducible in response to inflammatory signals. Thus, CCL20 is involved in both inflammatory and homeostatic functions in the immune system. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines. The CC chemokine receptors are all activating the G protein Gi. Pssm-ID: 341330 [Multi-domain] Cd Length: 281 Bit Score: 45.90 E-value: 2.21e-05

prolactin-releasing peptide receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; Prolactin-releasing peptide (PrRP) receptor (previously known as GPR10) is expressed in the central nervous system with the highest levels located in the anterior pituitary and is activated by its endogenous ligand PrRP, a neuropeptide possessing a C-terminal Arg-Phe-amide motif. There are two active isoforms of PrRP in mammals: one consists of 20 amino acids (PrRP-20) and the other consists of 31 amino acids (PrRP-31), where PrRP-20 is a C-terminal fragment of PrRP-31. Binding of PrRP to the receptor coupled to G(i/o) proteins activates the extracellular signal-related kinase (ERK) and it can also couple to G(q) protein leading to an increase in intracellular calcium and activation of c-Jun N-terminal protein kinase (JNK). The PrRP receptor shares significant sequence homology with the neuropeptide Y (NPY) receptor, and micromolar levels of NPY can bind and completely inhibit the PrRP-evoked intracellular calcium response in PrRP receptor-expressing cells, suggesting that the PrRP receptor shares a common ancestor with the NPY receptors. PrRP has been shown to reduce food intake and body weight and modify body temperature when administered in rats. It also has been shown to decrease circulating growth hormone levels by activating somatostatin-secreting neurons in the hypothalamic periventricular nucleus.

CXC chemokine receptor 7, member of the class A family of seven-transmembrane G protein-coupled receptors; ACKR3, also known as CXCR7, is an atypical chemokine receptor for CXCL12 and CXCR11. Unlike the classical chemokine receptors, ACKR3 contains a DRYLSIT-sequence instead of the conserved DRYLAIV motif in the second intracellular loop, which is required for G-protein coupling. Thus, ACKR3 does not activate classical GPCR signaling, instead induces beta-arrestin recruitment which is leading to ligand internalization and MAP-kinase activation. It is acting as a scavenger for CXCL12 and, to a lesser degree, for CXCL11. ACKR3 is highly expressed by blood vascular endothelial cells in brain, in numerous embryonic and neonatal tissues, in inflamed tissues and in a variety of cancers such as lymphomas, sarcomas, prostate and breast cancers, and gliomas. Five receptors have been identified for the ACKR family, including CC-Chemokine Receptors like 1 and 2 (CCRL1 and CCRL2), CXCR7, DARC, and D6.

G protein-coupled receptor 84 and similar proteins, member of the class A family of seven-transmembrane G protein-coupled receptors; GPR84, also known as the inflammation-related G-Protein coupled receptor EX33, is a receptor for medium-chain free fatty acid (FFA) with carbon chain lengths of C9 to C14. Among these medium-chain FFAs, capric acid (C10:0), undecanoic acid (C11:0), and lauric acid (C12:0) are the most potent endogenous agonists of GPR84, whereas short-chain and long-chain saturated and unsaturated FFAs do not activate this receptor. GPR84 contains a [G/N]RY-motif instead of the highly conserved Asp-Arg-Tyr (DRY) motif found in the third transmembrane helix (TM3) of the rhodopsin-like class A receptors and important for efficient G protein-coupled signal transduction. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, which then activate the heterotrimeric G proteins. In the case of GPR84, activation of the receptor couples to a pertussis toxin sensitive G(i/o)-protein pathway. GPR84 knockout mice showed increased Th2 cytokine production including IL-4, IL-5, and IL-13 compared to wild-type mice. It has been also shown that activation of GPR84 augments lipopolysaccharide-stimulated IL-8 production in polymorphonuclear leukocytes and TNF-alpha production in macrophages, suggesting that GPR84 may function as a proinflammatory receptor.

Atrophin-1 family; Atrophin-1 is the protein product of the dentatorubral-pallidoluysian atrophy (DRPLA) gene. DRPLA OMIM:125370 is a progressive neurodegenerative disorder. It is caused by the expansion of a CAG repeat in the DRPLA gene on chromosome 12p. This results in an extended polyglutamine region in atrophin-1, that is thought to confer toxicity to the protein, possibly through altering its interactions with other proteins. The expansion of a CAG repeat is also the underlying defect in six other neurodegenerative disorders, including Huntington's disease. One interaction of expanded polyglutamine repeats that is thought to be pathogenic is that with the short glutamine repeat in the transcriptional coactivator CREB binding protein, CBP. This interaction draws CBP away from its usual nuclear location to the expanded polyglutamine repeat protein aggregates that are characteriztic of the polyglutamine neurodegenerative disorders. This interferes with CBP-mediated transcription and causes cytotoxicity. Pssm-ID: 460830 [Multi-domain] Cd Length: 991 Bit Score: 45.91 E-value: 5.25e-05

CX3C chemokine receptor 1, member of the class A family of seven-transmembrane G protein-coupled receptors; CX3CR1 is an inflammatory receptor specific for CX3CL1 (also known as fractalkine in human), which is involved in the adhesion and migration of leukocytes. The CX3C chemokine subfamily is only represented by CX3CL1, which exists in both soluble and membrane-anchored forms. Membrane-anchored form promotes strong adhesion of receptor-bearing leukocytes to CX3CL1-expressing endothelial cells. On the other hand, soluble CX3CL1, which is released by the proteolytic cleavage of membrane-anchored CX3CL1, is a potent chemoattractant for CX3CR1-expressing T cells and monocytes. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Pssm-ID: 320314 [Multi-domain] Cd Length: 273 Bit Score: 44.05 E-value: 9.27e-05

cysteinyl leukotriene receptor 1, member of the class A family of seven-transmembrane G protein-coupled receptors; Cysteinyl leukotrienes (LTC4, LTD4, and LTE4) are the most potent inflammatory lipid mediators that play an important role in human asthma. They are synthesized in the leucocytes (cells of immune system) from arachidonic acid by the actions of 5-lipoxygenase and induce bronchial constriction through G protein-coupled receptors, CysLTR1 and CysLTR2. Activation of CysLTR1 by LTD4 induces airway smooth muscle contraction and proliferation, eosinophil migration, and damage to the lung tissue. They belong to the class A GPCR superfamily, which all have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

muscarinic acetylcholine receptor subtype M2, member of the class A family of seven-transmembrane G protein-coupled receptors; Muscarinic acetylcholine receptors (mAChRs) regulate the activity of many fundamental central and peripheral functions. The mAChR family consists of 5 subtypes M1-M5, which can be further divided into two major groups according to their G-protein coupling preference. The M1, M3 and M5 receptors selectively interact with G proteins of the G(q/11) family, whereas the M2 and M4 receptors preferentially link to the G(i/o) types of G proteins. Activation of M2 receptor causes a decrease in cAMP production, generally leading to inhibitory-type effects. This causes an outward current of potassium in the heart, resulting in a decreased heart rate. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits.

free fatty acid receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; This subfamily includes the free fatty acid receptors (FFARs) which bind free fatty acids (FFAs). They belong to the class A G-protein coupled receptors and are composed of three members, each encoded by a separate gene (FFAR1, FFAR2, and FFAR3). These genes and a fourth pseudogene, GPR42, are localized together on chromosome 19. FFAR1 is a receptor for medium- and long-chain FFAs, whereas FFAR2 and FFAR3 are receptors for short chain FFAs (SCFAs), which have different ligand affinities. FFAR1 directly mediates FFA stimulation of glucose-stimulated insulin secretion and also indirectly increases insulin secretion by enhancing the release of incretin. FFAR2 activation by SCFA suppresses adipose insulin signaling, which leads to the inhibition of fat accumulation in adipose tissue. FAAR3 is expressed in intestinal L cells, which produces glucagon-like peptide 1 (GLP-1) and peptide YY (PYY), suggesting that this receptor may be involved in energy homeostasis. FFARs are considered important components of the body's nutrient sensing mechanism, and therefore, these receptors are potential therapeutic targets for the treatment of metabolic disorders, such as type 2 diabetes and obesity.

Atrophin-1 family; Atrophin-1 is the protein product of the dentatorubral-pallidoluysian atrophy (DRPLA) gene. DRPLA OMIM:125370 is a progressive neurodegenerative disorder. It is caused by the expansion of a CAG repeat in the DRPLA gene on chromosome 12p. This results in an extended polyglutamine region in atrophin-1, that is thought to confer toxicity to the protein, possibly through altering its interactions with other proteins. The expansion of a CAG repeat is also the underlying defect in six other neurodegenerative disorders, including Huntington's disease. One interaction of expanded polyglutamine repeats that is thought to be pathogenic is that with the short glutamine repeat in the transcriptional coactivator CREB binding protein, CBP. This interaction draws CBP away from its usual nuclear location to the expanded polyglutamine repeat protein aggregates that are characteriztic of the polyglutamine neurodegenerative disorders. This interferes with CBP-mediated transcription and causes cytotoxicity. Pssm-ID: 460830 [Multi-domain] Cd Length: 991 Bit Score: 42.45 E-value: 6.43e-04

CC chemokine receptor types 5 and 2, member of the class A family of seven-transmembrane G protein-coupled receptors; CCR2 and CCR5 share very high amino acid sequence identity. Both receptors play important roles in the trafficking of monocytes/macrophages and are implicated in the pathogenesis of immunologic diseases (rheumatoid arthritis, celiac disease, and transplant rejection) and cardiovascular diseases (atherosclerosis and autoimmune hepatitis). CCR2 is a receptor specific for members of the monocyte chemotactic protein family, including CCL2, CCL7, and CCL13. Conversely, CCR5 is a major co-receptor for HIV infection and binds many CC chemokine ligands, including CC chemokine ligands including CCL2, CCL3, CCL4, CCL5, CCL11, CCL13, CCL14, and CCL16. CCR2 is expressed primarily on blood monocytes and memory T cells, whereas CCR5 is expressed on antigen-presenting cells (macrophages and dendritic cells) and activated T effector cells. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines.

muscarinic acetylcholine receptor subtype M4, member of the class A family of seven-transmembrane G protein-coupled receptors; Muscarinic acetylcholine receptors (mAChRs) regulate the activity of many fundamental central and peripheral functions. The mAChR family consists of 5 subtypes M1-M5, which can be further divided into two major groups according to their G-protein coupling preference. The M1, M3 and M5 receptors selectively interact with G proteins of the G(q/11) family, whereas the M2 and M4 receptors preferentially link to G(i/o) types of G proteins. The M4 receptor is mainly found in the CNS and function as an inhibitory autoreceptor regulating acetycholine release. All GPCRs have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes.

These homologous peptides of 36-amino acids in length contain a hairpin-like structural motif, which referred to as the pancreatic polypeptide fold, and function as gastrointestinal hormones and neurotransmitters. The PR4 receptor also shares strong sequence homology to the mammalian tachykinin receptors (NK1R, NK2R, and NK3R), whose endogenous ligands are substance P (SP), neurokinin A (NKA), and neurokinin B (NKB), respectively. The tachykinins function as excitatory transmitters on neurons and cells in the gastrointestinal tract. Pssm-ID: 320514 [Multi-domain] Cd Length: 287 Bit Score: 40.81 E-value: 1.07e-03

type 1 angiotensin II receptor, member of the class A family of seven-transmembrane G protein-coupled receptors; Angiotensin II (Ang II), the main effector in the renin-angiotensin system, plays a crucial role in the regulation of cardiovascular homeostasis through its type 1 (AT1) and type 2 (AT2) receptors. Ang II contributes to cardiovascular diseases such as hypertension and atherosclerosis via AT1R activation. Ang II increases blood pressure through Gq-mediated activation of phospholipase C, resulting in phosphoinositide (PI) hydrolysis and increased intracellular calcium levels. Through the AT2R, Ang II counteracts the vasoconstrictor action of AT1R and thereby induces vasodilation, sodium excretion, and reduction of blood pressure. Moreover, AT1R promotes cell proliferation, whereas AT2R inhibits proliferation and stimulates cell differentiation. The AT2R is highly expressed during fetal development, however it is scarcely present in adult tissues and is induced in pathological conditions. Generally, the AT1R mediates many actions of Ang II, while the AT2R is involved in the regulation of blood pressure and renal function.

Olfactory receptors (ORs) play a central role in olfaction, the sense of smell. ORs belong to the class A rhodopsin-like family of G protein-coupled receptors and constitute the largest multigene family in mammals of approximately 1,000 genes. More than 60% of human ORs are non-functional pseudogenes compared to only about 20% in mouse. Each OR can recognize structurally similar odorants, and a single odorant can be detected by several ORs. Binding of an odorant to the olfactory receptor induces a conformational change that leads to the activation of the olfactory-specific G protein (Golf). The G protein (Golf and/or Gs) in turn stimulates adenylate cyclase to make cAMP. The cAMP opens cyclic nucleotide-gated ion channels, which allow the influx of calcium and sodium ions, resulting in depolarization of the olfactory receptor neuron and triggering an action potential which transmits this information to the brain. A consensus nomenclature system based on evolutionary divergence is used here to classify the olfactory receptor family. The nomenclature begins with the root name OR, followed by an integer representing a family, a letter denoting a subfamily, and an integer representing the individual gene within the subfamily.

Kinetoplastid RNA Editing Protein A2 (KREPA2); The KREPA2 (TbMP63) protein is a component of the parasitic protozoan's KREPA RNA editing catalytic complex (RECC). Kinetoplastid RNA editing (KRE) proteins occur as pairs or sets of related proteins in multiple complexes. KREPA complex is composed of six components (KREPA1-6), which share a conserved C-terminal region containing an oligonucleotide-binding (OB)-fold-like domain. KREPAs are responsible for the site-specific insertion and deletion of U nucleotides in the kinetoplastid mitochondria pre-messenger RNA. Apart from the conserved C-terminal OB-fold domain, KREPA1, KREPA2, and KREPA3 contain two conserved C2H2 zinc-finger domains. KREPA2 and kinetoplastid RNA editing ligase 1 (KREL1) are specific for ligation post-U-deletion and are paralogous to KREL2 and KREPA1 that are specific for ligation post-U-insertion. KREPA2, is critical for RECC stability and KREL1 integration into the complex. Pssm-ID: 467780 [Multi-domain] Cd Length: 424 Bit Score: 41.01 E-value: 1.50e-03

D2-like dopamine receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Dopamine receptors are members of the class A G protein-coupled receptors that are involved in many neurological processes in the central nervous system (CNS). The neurotransmitter dopamine is the primary endogenous agonist for dopamine receptors. Dopamine receptors consist of at least five subtypes: D1, D2, D3, D4, and D5. The D1 and D5 subtypes are members of the D1-like family of dopamine receptors, whereas the D2, D3 and D4 subtypes are members of the D2-like family. The D1-like family receptors are coupled to G proteins of the G(s) family, which activate adenylate cyclase, causing cAMP formation and activation of protein kinase A. In contrast, activation of D2-like family receptors is linked to G proteins of the G(i) family, which inhibit adenylate cyclase. Dopamine receptors are major therapeutic targets for neurological and psychiatric disorders such as drug abuse, depression, schizophrenia, or Parkinson's disease.

Four different types of the protease-activated receptors have been identified: PAR1, PAR2, PAR3, and PAR4. PARs are predominantly expressed in platelets and are activated by serine proteases such as thrombin, trypsin, and tryptase. These proteases cleave the extracellular domain of the receptor to form a new N-terminus, which in turn functions as a tethered ligand. The newly-formed tethered ligand binds intramolecularly to activate the receptor and triggers G-protein binding and intracellular signaling. PAR1, PA3, and PAR4 are activated by thrombin, whereas PAR2 is activated by trypsin. The PARs are known to couple with several G-proteins including Gi (cAMP inhibitory), G12/13 (Rho and Ras activation), and Gq (calcium signaling) to activate downstream signaling messengers which induces numerous cellular and physiological effects.

cholecystokinin receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; Cholecystokinin receptors (CCK-AR and CCK-BR) are a group of G-protein coupled receptors which bind the peptide hormones cholecystokinin (CCK) or gastrin. CCK, which facilitates digestion in the small intestine, and gastrin, a major regulator of gastric acid secretion, are highly similar peptides. Like gastrin, CCK is a naturally-occurring linear peptide that is synthesized as a preprohormone, then proteolytically cleaved to form a family of peptides with the common C-terminal sequence (Gly-Trp-Met-Asp-Phe-NH2), which is required for full biological activity. CCK-AR (type A, alimentary; also known as CCK1R) is found abundantly on pancreatic acinar cells and binds only sulfated CCK-peptides with very high affinity, whereas CCK-BR (type B, brain; also known as CCK2R), the predominant form in the brain and stomach, binds CCK or gastrin and discriminates poorly between sulfated and non-sulfated peptides. CCK is implicated in regulation of digestion, appetite control, and body weight, and is involved in neurogenesis via CCK-AR. There is some evidence to support that CCK and gastrin, via their receptors, are involved in promoting cancer development and progression, acting as growth and invasion factors.

Four different types of the protease-activated receptors have been identified: PAR1, PAR2, PAR3, and PAR4. PARs are predominantly expressed in platelets and are activated by serine proteases such as thrombin, trypsin, and tryptase. These proteases cleave the extracellular domain of the receptor to form a new N-terminus, which in turn functions as a tethered ligand. The newly-formed tethered ligand binds intramolecularly to activate the receptor and triggers G-protein binding and intracellular signaling. PAR1, PA3, and PAR4 are activated by thrombin, whereas PAR2 is activated by trypsin. The PARs are known to couple with several G-proteins including Gi (cAMP inhibitory), G12/13 (Rho and Ras activation), and Gq (calcium signaling) to activate downstream signaling messengers which induces numerous cellular and physiological effects.

MAS1L is a G protein-coupled receptor that only found in primates. The angiotensin-II metabolite angiotensin is an endogenous ligand for MAS1L. The Mas-related G-protein coupled receptor (Mrgpr) family constitutes a group of orphan receptors exclusively expressed in nociceptive primary sensory neurons and mast cells in the skin. Members of the Mrgpr family have been implicated in the modulation of nociception, pruritus (itching), and mast cell degranulation. The Mrgpr family in rodents and humans contains more than 50 members that can be grouped into 9 distinct subfamilies: MrgprA, B, C (MrgprX1), D, E, F, G, H (GPR90), and the primate-specific MrgprX subfamily. Some Mrgprs can be activated by endogenous ligands such as beta-alanine, adenine (a cell metabolite and potential transmitter), RF-amide related peptides, or salusin-beta (a bioactive peptide). However, the effects of these agonists are not clearly understood, and the physiological role of the individual receptor family members remains to be determined.

The tachykinins are widely distributed throughout the mammalian central and peripheral nervous systems and act as excitatory transmitters on neurons and cells in the gastrointestinal tract. The TKs are characterized by a common five-amino acid C-terminal sequence, Phe-X-Gly-Leu-Met-NH2, where X is a hydrophobic residue. The three major mammalian tachykinins are substance P (SP), neurokinin A (NKA), and neurokinin B (NKB). The physiological actions of tachykinins are mediated through three types of receptors: neurokinin receptor type 1 (NK1R), NK2R, and NK3R. SP is a high-affinity endogenous ligand for NK1R, which interacts with the Gq protein and activates phospholipase C, leading to elevation of intracellular calcium. NK2R is a high-affinity receptor for NKA, the tachykinin neuropeptide substance K. SP and NKA are found in the enteric nervous system and mediate in the regulation of gastrointestinal motility, secretion, vascular permeability, and pain perception. NK3R is activated by its high-affinity ligand, NKB, which is primarily involved in the central nervous system and plays a critical role in the regulation of gonadotropin hormone release and the onset of puberty.

serotonin receptor subtype 2, member of the class A family of seven-transmembrane G protein-coupled receptors; The 5-HT2 receptors are a subfamily of serotonin receptors that bind the neurotransmitter serotonin (5HT; 5-hydroxytryptamine) in the central nervous system (CNS). The 5-HT2 subfamily is composed of three subtypes that mediate excitatory neurotransmission: 5-HT2A, 5-HT2B, and 5-HT2C. They are selectively linked to G proteins of the G(q/11) family and activate phospholipase C, which leads to activation of protein kinase C and calcium release. In the CNS, serotonin is involved in the regulation of appetite, mood, sleep, cognition, learning and memory, as well as implicated in diseases such as migraine, schizophrenia, and depression. Indeed, 5-HT2 receptors are attractive targets for a variety of psychoactive drugs, ranging from atypical antipsychotic drugs, antidepressants, and anxiolytics, which have an antagonistic action on 5-HT2 receptors, to hallucinogens, which act as agonists at postsynaptic 5-HT2 receptors.

Urotensin II (UII) is a vasoactive somatostatin-like or cortistatin-like peptide hormone. However, despite the apparent structural similarity to these peptide hormones, they are not homologous to UII. Urotensin II was first identified in fish spinal cord, but later found in humans and other mammals. In fish, UII is secreted at the back part of the spinal cord, in a neurosecretory centre called uroneurapophysa, and is involved in the regulation of the renal and cardiovascular systems. In mammals, urotensin II is the most potent mammalian vasoconstrictor identified to date and causes contraction of arterial blood vessels, including the thoracic aorta. The urotensin II receptor is a rhodopsin-like G-protein coupled receptor, which binds urotensin-II. The receptor was previously known as GPR14, or sensory epithelial neuropeptide-like receptor (SENR). The UII receptor is expressed in the CNS (cerebellum and spinal cord), skeletal muscle, pancreas, heart, endothelium and vascular smooth muscle. It is involved in the pathophysiological control of cardiovascular function and may also influence CNS and endocrine functions. Binding of urotensin II to the receptor leads to activation of phospholipase C, through coupling to G(q/11) family proteins. The resulting increase in intracellular calcium may cause the contraction of vascular smooth muscle. Pssm-ID: 320130 [Multi-domain] Cd Length: 282 Bit Score: 38.96 E-value: 4.27e-03

seven-transmembrane G protein-coupled receptor superfamily; This hierarchical evolutionary model represents the seven-transmembrane (7TM) receptors, often referred to as G protein-coupled receptors (GPCRs), which transmit physiological signals from the outside of the cell to the inside via G proteins. GPCRs constitute the largest known superfamily of transmembrane receptors across the three kingdoms of life that respond to a wide variety of extracellular stimuli including peptides, lipids, neurotransmitters, amino acids, hormones, and sensory stimuli such as light, smell and taste. All GPCRs share a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes. However, some 7TM receptors, such as the type 1 microbial rhodopsins, do not activate G proteins. Based on sequence similarity, GPCRs can be divided into six major classes: class A (the rhodopsin-like family), class B (the Methuselah-like, adhesion and secretin-like receptor family), class C (the metabotropic glutamate receptor family), class D (the fungal mating pheromone receptors), class E (the cAMP receptor family), and class F (the frizzled/smoothened receptor family). Nearly 800 human GPCR genes have been identified and are involved essentially in all major physiological processes. Approximately 40% of clinically marketed drugs mediate their effects through modulation of GPCR function for the treatment of a variety of human diseases including bacterial infections.

CC chemokine receptor type 8, member of the class A family of seven-transmembrane G protein-coupled receptors; CCR8, the receptor for the CC chemokines CCL1 and CC16, is highly expressed on allergen-specific T-helper type 2 cells, and is implicated in the pathogenesis of human asthma. CCL1- and CCR8-expressing CD4+ effector T lymphocytes are shown to have a critical role in lung mucosal inflammatory responses. CCR8 is also a functional receptor for CCL16, a liver-expressed CC chemokine that involved in attracting lymphocytes, dendritic cells, and monocytes. Chemokines are principal regulators for leukocyte trafficking, recruitment, and activation. Chemokine family membership is defined on the basis of sequence homology and on the presence of variations on a conserved cysteine motif, which allows the family to further divide into four subfamilies (CC, CXC, XC, and CX3C). Chemokines interact with seven-transmembrane receptors which are typically coupled to G protein for signaling. Currently, there are ten known receptors for CC chemokines, seven for CXC chemokines, and single receptors for the XC and CX3C chemokines.

GPR35 shares closest homology with GPR55, and they belong to the class A G protein-coupled receptor superfamily, which all have a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A number of studies have suggested that GPR35 may play important physiological roles in hypertension, atherosclerosis, nociception, asthma, glucose homeostasis and diabetes, and inflammatory bowel disease. GPR35 is thought to be responsible for brachydactyly mental retardation syndrome, which is associated with a deletion comprising chromosome 2q37 in human, and is also implicated as a potential oncogene in stomach cancer. GPR35 couples to G(13) and G(i/o) proteins, whereas GPR55 has been reported to couple to G(13), G(12), or G(q) proteins. Activation of GPR55 leads to activation of phospholipase C, RhoA, ROCK, ERK, p38MAPK, and calcium release. Recently, lysophosphatidylinositol (LPI) has been identified as an endogenous ligand for GPR55, while several endogenous ligands for GPR35 have been identified including kynurenic acid, 2-oleoyl lysophosphatidic acid, and zaprinast.

Atrophin-1 family; Atrophin-1 is the protein product of the dentatorubral-pallidoluysian atrophy (DRPLA) gene. DRPLA OMIM:125370 is a progressive neurodegenerative disorder. It is caused by the expansion of a CAG repeat in the DRPLA gene on chromosome 12p. This results in an extended polyglutamine region in atrophin-1, that is thought to confer toxicity to the protein, possibly through altering its interactions with other proteins. The expansion of a CAG repeat is also the underlying defect in six other neurodegenerative disorders, including Huntington's disease. One interaction of expanded polyglutamine repeats that is thought to be pathogenic is that with the short glutamine repeat in the transcriptional coactivator CREB binding protein, CBP. This interaction draws CBP away from its usual nuclear location to the expanded polyglutamine repeat protein aggregates that are characteriztic of the polyglutamine neurodegenerative disorders. This interferes with CBP-mediated transcription and causes cytotoxicity. Pssm-ID: 460830 [Multi-domain] Cd Length: 991 Bit Score: 39.37 E-value: 6.00e-03

Kruppel-like factor (KLF) 9, KLF13, KLF14, KLF16, and similar proteins; Kruppel/Krueppel-like transcription factors (KLFs) belong to a family of proteins, called the Specificity Protein (SP)/KLF family, characterized by a C-terminal DNA-binding domain of 81 amino acids consisting of three Kruppel-like C2H2 zinc fingers. These factors bind to a loose consensus motif, namely NNRCRCCYY (where N is any nucleotide; R is A/G, and Y is C/T), such as the recurring motifs in GC and GT boxes (5'-GGGGCGGGG-3' and 5-GGTGTGGGG-3') that are present in promoters and more distal regulatory elements of mammalian genes. Members of the KLF family can act as activators or repressors of transcription depending on cell and promoter context. KLFs regulate various cellular functions, such as proliferation, differentiation, and apoptosis, as well as the development and homeostasis of several types of tissue. KLF9, KLF10, KLF11, KLF13, KLF14, and KLF16 share a conserved alpha-helical motif AA/VXXL that mediates their binding to Sin3A and their activities as transcriptional repressors. In addition to the C-terminal DNA-binding domain, each KLF also has a unique N-terminal activation/repression domain that confers specificity and allows it to bind specifically to a certain partner, leading to distinct activities in vivo. This model represents the related N-terminal domains of KLF9, KLF13, KLF14, KLF16, and similar proteins. Pssm-ID: 409240 [Multi-domain] Cd Length: 163 Bit Score: 37.36 E-value: 7.40e-03

tachykinin receptors and related receptors, member of the class A family of seven-transmembrane G protein-coupled receptors; This group includes the neurokinin/tachykinin receptors and its closely related receptors such as orphan GPR83 and leucokinin-like peptide receptor. The tachykinins are widely distributed throughout the mammalian central and peripheral nervous systems and act as excitatory transmitters on neurons and cells in the gastrointestinal tract. The TKs are characterized by a common five-amino acid C-terminal sequence, Phe-X-Gly-Leu-Met-NH2, where X is a hydrophobic residue. The three major mammalian tachykinins are substance P (SP), neurokinin A (NKA), and neurokinin B (NKB). The physiological actions of tachykinins are mediated through three types of receptors: neurokinin receptor type 1 (NK1R), NK2R, and NK3R. SP is a high-affinity endogenous ligand for NK1R, which interacts with the Gq protein and activates phospholipase C, leading to elevation of intracellular calcium. NK2R is a high-affinity receptor for NKA, the tachykinin neuropeptide substance K. SP and NKA are found in the enteric nervous system and mediate in the regulation of gastrointestinal motility, secretion, vascular permeability, and pain perception. NK3R is activated by its high-affinity ligand, NKB, which is primarily involved in the central nervous system and plays a critical role in the regulation of gonadotropin hormone release and the onset of puberty.
