RhoBTB protein is an atypical member of the Rho family of small GTPases; Members of the RhoBTB subfamily of Rho GTPases are present in vertebrates, Drosophila, and Dictyostelium. RhoBTB proteins are characterized by a modular organization, consisting of a GTPase domain, a proline rich region, a tandem of two BTB (Broad-Complex, Tramtrack, and Bric a brac) domains, and a C-terminal region of unknown function. RhoBTB proteins may act as docking points for multiple components participating in signal transduction cascades. RhoBTB genes appeared upregulated in some cancer cell lines, suggesting a participation of RhoBTB proteins in the pathogenesis of particular tumors. Note that the Dictyostelium RacA GTPase domain is more closely related to Rac proteins than to RhoBTB proteins, where RacA actually belongs. Thus, the Dictyostelium RacA is not included here. Most Rho proteins contain a lipid modification site at the C-terminus; however, RhoBTB is one of few Rho subfamilies that lack this feature. : Pssm-ID: 133275 [Multi-domain] Cd Length: 195 Bit Score: 398.96 E-value: 1.55e-136

second BTB (Broad-Complex, Tramtrack and Bric a brac)/POZ (poxvirus and zinc finger) domain found in Rho-related BTB domain-containing protein 1 (RhoBTB1); RhoBTB1 is an atypical Rho family small guanosine triphosphatase (GTPase) and is a member of the RhoBTB subfamily, which is characterized by containing a GTPase domain (in most cases, non-functional) followed by a proline-rich region, tandem BTB domains, and a conserved C-terminal region. The carboxyl terminal extension that harbors two BTB domains is capable of assembling cullin 3-dependent ubiquitin ligase complexes. RhoBTB1 functions as a tumor suppressor that regulates the integrity of the Golgi complex through the methyltransferase METTL7B. It also acts an adaptor of the Cullin-3-dependent E3 ubiquitin ligase complex. This model corresponds to the second BTB domain. The BTB/POZ domain is a common protein-protein interaction motif of about 100 amino acids. : Pssm-ID: 349667 [Multi-domain] Cd Length: 126 Bit Score: 279.54 E-value: 2.82e-91

BTB/POZ domain; The BTB (for BR-C, ttk and bab) or POZ (for Pox virus and Zinc finger) domain is present near the N-terminus of a fraction of zinc finger (pfam00096) proteins and in proteins that contain the pfam01344 motif such as Kelch and a family of pox virus proteins. The BTB/POZ domain mediates homomeric dimerization and in some instances heteromeric dimerization. The structure of the dimerized PLZF BTB/POZ domain has been solved and consists of a tightly intertwined homodimer. The central scaffolding of the protein is made up of a cluster of alpha-helices flanked by short beta-sheets at both the top and bottom of the molecule. POZ domains from several zinc finger proteins have been shown to mediate transcriptional repression and to interact with components of histone deacetylase co-repressor complexes including N-CoR and SMRT. The POZ or BTB domain is also known as BR-C/Ttk or ZiN. Pssm-ID: 395526 [Multi-domain] Cd Length: 107 Bit Score: 75.37 E-value: 1.78e-16

Ras homology family (Rho) of small guanosine triphosphatases (GTPases); Members of the Rho (Ras homology) family include RhoA, Cdc42, Rac, Rnd, Wrch1, RhoBTB, and Rop. There are 22 human Rho family members identified currently. These proteins are all involved in the reorganization of the actin cytoskeleton in response to external stimuli. They also have roles in cell transformation by Ras in cytokinesis, in focal adhesion formation and in the stimulation of stress-activated kinase. These various functions are controlled through distinct effector proteins and mediated through a GTP-binding/GTPase cycle involving three classes of regulating proteins: GAPs (GTPase-activating proteins), GEFs (guanine nucleotide exchange factors), and GDIs (guanine nucleotide dissociation inhibitors). Most Rho proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid. Lipid binding is essential for membrane attachment, a key feature of most Rho proteins. Since crystal structures often lack C-terminal residues, this feature is not available for annotation in many of the CDs in the hierarchy.

Ras homology family 4 (Rho4) of small guanosine triphosphatases (GTPases)-like; Rho4 is a GTPase that controls septum degradation by regulating secretion of Eng1 or Agn1 during cytokinesis. Rho4 also plays a role in cell morphogenesis. Rho4 regulates septation and cell morphology by controlling the actin cytoskeleton and cytoplasmic microtubules. The localization of Rho4 is modulated by Rdi1, which may function as a GDI, and by Rga9, which is believed to function as a GAP. In S. pombe, both Rho4 deletion and Rho4 overexpression result in a defective cell wall, suggesting a role for Rho4 in maintaining cell wall integrity. Most Rho proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid. Lipid binding is essential for membrane attachment, a key feature of most Rho proteins. Pssm-ID: 206704 [Multi-domain] Cd Length: 197 Bit Score: 155.58 E-value: 1.39e-43

Ras homolog family, member G (RhoG) of small guanosine triphosphatases (GTPases); RhoG is a GTPase with high sequence similarity to members of the Rac subfamily, including the regions involved in effector recognition and binding. However, RhoG does not bind to known Rac1 and Cdc42 effectors, including proteins containing a Cdc42/Rac interacting binding (CRIB) motif. Instead, RhoG interacts directly with Elmo, an upstream regulator of Rac1, in a GTP-dependent manner and forms a ternary complex with Dock180 to induce activation of Rac1. The RhoG-Elmo-Dock180 pathway is required for activation of Rac1 and cell spreading mediated by integrin, as well as for neurite outgrowth induced by nerve growth factor. Thus RhoG activates Rac1 through Elmo and Dock180 to control cell morphology. RhoG has also been shown to play a role in caveolar trafficking and has a novel role in signaling the neutrophil respiratory burst stimulated by G protein-coupled receptor (GPCR) agonists. Most Rho proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid. Lipid binding is essential for membrane attachment, a key feature of most Rho proteins. Pssm-ID: 133277 [Multi-domain] Cd Length: 191 Bit Score: 148.23 E-value: 5.20e-41

Ras-related C3 botulinum toxin substrate 1 (rho family, small GTP binding protein Rac1)-like consists of Rac1, Rac2 and Rac3; The Rac1-like subfamily consists of Rac1, Rac2, and Rac3 proteins, plus the splice variant Rac1b that contains a 19-residue insertion near switch II relative to Rac1. While Rac1 is ubiquitously expressed, Rac2 and Rac3 are largely restricted to hematopoietic and neural tissues respectively. Rac1 stimulates the formation of actin lamellipodia and membrane ruffles. It also plays a role in cell-matrix adhesion and cell anoikis. In intestinal epithelial cells, Rac1 is an important regulator of migration and mediates apoptosis. Rac1 is also essential for RhoA-regulated actin stress fiber and focal adhesion complex formation. In leukocytes, Rac1 and Rac2 have distinct roles in regulating cell morphology, migration, and invasion, but are not essential for macrophage migration or chemotaxis. Rac3 has biochemical properties that are closely related to Rac1, such as effector interaction, nucleotide binding, and hydrolysis; Rac2 has a slower nucleotide association and is more efficiently activated by the RacGEF Tiam1. Both Rac1 and Rac3 have been implicated in the regulation of cell migration and invasion in human metastatic breast cancer. Most Rho proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid. Lipid binding is essential for membrane attachment, a key feature of most Rho proteins.

Wnt-1 responsive Cdc42 homolog (Wrch-1) is a Rho family GTPase similar to Cdc42; Wrch-1 (Wnt-1 responsive Cdc42 homolog) is a Rho family GTPase that shares significant sequence and functional similarity with Cdc42. Wrch-1 was first identified in mouse mammary epithelial cells, where its transcription is upregulated in Wnt-1 transformation. Wrch-1 contains N- and C-terminal extensions relative to cdc42, suggesting potential differences in cellular localization and function. The Wrch-1 N-terminal extension contains putative SH3 domain-binding motifs and has been shown to bind the SH3 domain-containing protein Grb2, which increases the level of active Wrch-1 in cells. Unlike Cdc42, which localizes to the cytosol and perinuclear membranes, Wrch-1 localizes extensively with the plasma membrane and endosomes. The membrane association, localization, and biological activity of Wrch-1 indicate an atypical model of regulation distinct from other Rho family GTPases. Most Rho proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid.

cell division cycle 42 (Cdc42) is a small GTPase of the Rho family; Cdc42 is an essential GTPase that belongs to the Rho family of Ras-like GTPases. These proteins act as molecular switches by responding to exogenous and/or endogenous signals and relaying those signals to activate downstream components of a biological pathway. Cdc42 transduces signals to the actin cytoskeleton to initiate and maintain polarized growth and to mitogen-activated protein morphogenesis. In the budding yeast Saccharomyces cerevisiae, Cdc42 plays an important role in multiple actin-dependent morphogenetic events such as bud emergence, mating-projection formation, and pseudohyphal growth. In mammalian cells, Cdc42 regulates a variety of actin-dependent events and induces the JNK/SAPK protein kinase cascade, which leads to the activation of transcription factors within the nucleus. Cdc42 mediates these processes through interactions with a myriad of downstream effectors, whose number and regulation we are just starting to understand. In addition, Cdc42 has been implicated in a number of human diseases through interactions with its regulators and downstream effectors. Most Rho proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid.

Ras homology family A (RhoA)-like includes RhoA, RhoB and RhoC; The RhoA subfamily consists of RhoA, RhoB, and RhoC. RhoA promotes the formation of stress fibers and focal adhesions, regulating cell shape, attachment, and motility. RhoA can bind to multiple effector proteins, thereby triggering different downstream responses. In many cell types, RhoA mediates local assembly of the contractile ring, which is necessary for cytokinesis. RhoA is vital for muscle contraction; in vascular smooth muscle cells, RhoA plays a key role in cell contraction, differentiation, migration, and proliferation. RhoA activities appear to be elaborately regulated in a time- and space-dependent manner to control cytoskeletal changes. Most Rho proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid. Lipid binding is essential for membrane attachment, a key feature of most Rho proteins. RhoA and RhoC are observed only in geranylgeranylated forms; however, RhoB can be present in palmitoylated, farnesylated, and geranylgeranylated forms. RhoA and RhoC are highly relevant for tumor progression and invasiveness; however, RhoB has recently been suggested to be a tumor suppressor. Due to the presence of truncated sequences in this CD, the lipid modification site is not available for annotation. Pssm-ID: 206662 [Multi-domain] Cd Length: 175 Bit Score: 126.77 E-value: 1.47e-33

Most Rho proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid. Lipid binding is essential for proper intracellular localization via membrane attachment. As with other Rho family GTPases, the GDP/GTP cycling is regulated by GEFs (guanine nucleotide exchange factors), GAPs (GTPase-activating proteins) and GDIs (guanine nucleotide dissociation inhibitors).

Rho GTPase TC10 (Tc10); TC10 is a Rho family protein that has been shown to induce microspike formation and neurite outgrowth in vitro. Its expression changes dramatically after peripheral nerve injury, suggesting an important role in promoting axonal outgrowth and regeneration. TC10 regulates translocation of insulin-stimulated GLUT4 in adipocytes and has also been shown to bind directly to Golgi COPI coat proteins. GTP-bound TC10 in vitro can bind numerous potential effectors. Depending on its subcellular localization and distinct functional domains, TC10 can differentially regulate two types of filamentous actin in adipocytes. TC10 mRNAs are highly expressed in three types of mouse muscle tissues: leg skeletal muscle, cardiac muscle, and uterus; they were also present in brain, with higher levels in adults than in newborns. TC10 has also been shown to play a role in regulating the expression of cystic fibrosis transmembrane conductance regulator (CFTR) through interactions with CFTR-associated ligand (CAL). The GTP-bound form of TC10 directs the trafficking of CFTR from the juxtanuclear region to the secretory pathway toward the plasma membrane, away from CAL-mediated DFTR degradation in the lysosome.

Rho-related protein from plants (Rop)-like; The Rop (Rho-related protein from plants) subfamily plays a role in diverse cellular processes, including cytoskeletal organization, pollen and vegetative cell growth, hormone responses, stress responses, and pathogen resistance. Rops are able to regulate several downstream pathways to amplify a specific signal by acting as master switches early in the signaling cascade. They transmit a variety of extracellular and intracellular signals. Rops are involved in establishing cell polarity in root-hair development, root-hair elongation, pollen-tube growth, cell-shape formation, responses to hormones such as abscisic acid (ABA) and auxin, responses to abiotic stresses such as oxygen deprivation, and disease resistance and disease susceptibility. An individual Rop can have a unique function or an overlapping function shared with other Rop proteins; in addition, a given Rop-regulated function can be controlled by one or multiple Rop proteins. For example, Rop1, Rop3, and Rop5 are all involved in pollen-tube growth; Rop2 plays a role in response to low-oxygen environments, cell-morphology, and root-hair development; root-hair development is also regulated by Rop4 and Rop6; Rop6 is also responsible for ABA response, and ABA response is also regulated by Rop10. Plants retain some of the regulatory mechanisms that are shared by other members of the Rho family, but have also developed a number of unique modes for regulating Rops. Unique RhoGEFs have been identified that are exclusively active toward Rop proteins, such as those containing the domain PRONE (plant-specific Rop nucleotide exchanger). Most Rho proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid.

Rnd3/RhoE/Rho8 GTPases; Rnd3/RhoE/Rho8 subfamily. Rnd3/RhoE/Rho8 is a member of the novel Rho subfamily Rnd, together with Rnd1/Rho6 and Rnd2/Rho7. Rnd3/RhoE is known to bind the serine-threonine kinase ROCK I. Unphosphorylated Rnd3/RhoE associates primarily with membranes, but ROCK I-phosphorylated Rnd3/RhoE localizes in the cytosol. Phosphorylation of Rnd3/RhoE correlates with its activity in disrupting RhoA-induced stress fibers and inhibiting Ras-induced fibroblast transformation. In cells that lack stress fibers, such as macrophages and monocytes, Rnd3/RhoE induces a redistribution of actin, causing morphological changes in the cell. In addition, Rnd3/RhoE has been shown to inhibit cell cycle progression in G1 phase at a point upstream of the pRb family pocket protein checkpoint. Rnd3/RhoE has also been shown to inhibit Ras- and Raf-induced fibroblast transformation. In mammary epithelial tumor cells, Rnd3/RhoE regulates the assembly of the apical junction complex and tight junction formation. Rnd3/RhoE is underexpressed in prostate cancer cells both in vitro and in vivo; re-expression of Rnd3/RhoE suppresses cell cycle progression and increases apoptosis, suggesting it may play a role in tumor suppression.

Rnd2/Rho7 GTPases; Rnd2/Rho7 is a member of the novel Rho subfamily Rnd, together with Rnd1/Rho6 and Rnd3/RhoE/Rho8. Rnd2/Rho7 is transiently expressed in radially migrating cells in the brain while they are within the subventricular zone of the hippocampus and cerebral cortex. These migrating cells typically develop into pyramidal neurons. Cells that exogenously expressed Rnd2/Rho7 failed to migrate to upper layers of the brain, suggesting that Rnd2/Rho7 plays a role in the radial migration and morphological changes of developing pyramidal neurons, and that Rnd2/Rho7 degradation is necessary for proper cellular migration. The Rnd2/Rho7 GEF Rapostlin is found primarily in the brain and together with Rnd2/Rho7 induces dendrite branching. Unlike Rnd1/Rho6 and Rnd3/RhoE/Rho8, which are RhoA antagonists, Rnd2/Rho7 binds the GEF Pragmin and significantly stimulates RhoA activity and Rho-A mediated cell contraction. Rnd2/Rho7 is also found to be expressed in spermatocytes and early spermatids, with male-germ-cell Rac GTPase-activating protein (MgcRacGAP), where it localizes to the Golgi-derived pro-acrosomal vesicle.

Ras-related in brain (Rab) family of small guanosine triphosphatases (GTPases); Rab GTPases form the largest family within the Ras superfamily. There are at least 60 Rab genes in the human genome, and a number of Rab GTPases are conserved from yeast to humans. Rab GTPases are small, monomeric proteins that function as molecular switches to regulate vesicle trafficking pathways. The different Rab GTPases are localized to the cytosolic face of specific intracellular membranes, where they regulate distinct steps in membrane traffic pathways. In the GTP-bound form, Rab GTPases recruit specific sets of effector proteins onto membranes. Through their effectors, Rab GTPases regulate vesicle formation, actin- and tubulin-dependent vesicle movement, and membrane fusion. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which mask C-terminal lipid binding and promote cytosolic localization. While most unicellular organisms possess 5-20 Rab members, several have been found to possess 60 or more Rabs; for many of these Rab isoforms, homologous proteins are not found in other organisms. Most Rab GTPases contain a lipid modification site at the C-terminus, with sequence motifs CC, CXC, or CCX. Lipid binding is essential for membrane attachment, a key feature of most Rab proteins. Since crystal structures often lack C-terminal residues, the lipid modification site is not available for annotation in many of the CDs in the hierarchy, but is included where possible.

Rho3 is also believed to have a direct role in exocytosis that is independent of its role in regulating actin polarity. The function in exocytosis may be two-pronged: first, in the transport of post-Golgi vesicles from the mother cell to the bud, mediated by myosin (Myo2); second, in the docking and fusion of vesicles to the plasma membrane, mediated by an exocyst (Exo70) protein.

BTB/POZ domain; The BTB (for BR-C, ttk and bab) or POZ (for Pox virus and Zinc finger) domain is present near the N-terminus of a fraction of zinc finger (pfam00096) proteins and in proteins that contain the pfam01344 motif such as Kelch and a family of pox virus proteins. The BTB/POZ domain mediates homomeric dimerization and in some instances heteromeric dimerization. The structure of the dimerized PLZF BTB/POZ domain has been solved and consists of a tightly intertwined homodimer.

Rat sarcoma (Ras)-like superfamily of small guanosine triphosphatases (GTPases); Ras-like GTPase superfamily. The Ras-like superfamily of small GTPases consists of several families with an extremely high degree of structural and functional similarity. The Ras superfamily is divided into at least four families in eukaryotes: the Ras, Rho, Rab, and Sar1/Arf families. This superfamily also includes proteins like the GTP translation factors, Era-like GTPases, and G-alpha chain of the heterotrimeric G proteins. Members of the Ras superfamily regulate a wide variety of cellular functions: the Ras family regulates gene expression, the Rho family regulates cytoskeletal reorganization and gene expression, the Rab and Sar1/Arf families regulate vesicle trafficking, and the Ran family regulates nucleocytoplasmic transport and microtubule organization. The GTP translation factor family regulates initiation, elongation, termination, and release in translation, and the Era-like GTPase family regulates cell division, sporulation, and DNA replication. Members of the Ras superfamily are identified by the GTP binding site, which is made up of five characteristic sequence motifs, and the switch I and switch II regions.

Ras proteins regulate cell growth, proliferation and differentiation. Ras is activated by guanine nucleotide exchange factors (GEFs) that release GDP and allow GTP binding. Many RasGEFs have been identified. These are sequestered in the cytosol until activation by growth factors triggers recruitment to the plasma membrane or Golgi, where the GEF colocalizes with Ras. Active GTP-bound Ras interacts with several effector proteins: among the best characterized are the Raf kinases, phosphatidylinositol 3-kinase (PI3K), RalGEFs and NORE/MST1. Most Ras proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid.

Rab6A of mammals is implicated in retrograde transport through the Golgi stack, and is also required for a slow, COPI-independent, retrograde transport pathway from the Golgi to the endoplasmic reticulum (ER). This pathway may allow Golgi residents to be recycled through the ER for scrutiny by ER quality-control systems. Yeast Ypt6p, the homolog of the mammalian Rab6 GTPase, is not essential for cell viability. Ypt6p acts in endosome-to-Golgi, in intra-Golgi retrograde transport, and possibly also in Golgi-to-ER trafficking.

Ras GTPase family containing H-Ras,N-Ras and K-Ras4A/4B; H-Ras/N-Ras/K-Ras subfamily. H-Ras, N-Ras, and K-Ras4A/4B are the prototypical members of the Ras family. These isoforms generate distinct signal outputs despite interacting with a common set of activators and effectors, and are strongly associated with oncogenic progression in tumor initiation. Mutated versions of Ras that are insensitive to GAP stimulation (and are therefore constitutively active) are found in a significant fraction of human cancers. Many Ras guanine nucleotide exchange factors (GEFs) have been identified. They are sequestered in the cytosol until activation by growth factors triggers recruitment to the plasma membrane or Golgi, where the GEF colocalizes with Ras. Active (GTP-bound) Ras interacts with several effector proteins that stimulate a variety of diverse cytoplasmic signaling activities. Some are known to positively mediate the oncogenic properties of Ras, including Raf, phosphatidylinositol 3-kinase (PI3K), RalGEFs, and Tiam1. Others are proposed to play negative regulatory roles in oncogenesis, including RASSF and NORE/MST1.

Rab GTPase family 23 (Rab23)-like; Rab23-like subfamily. Rab23 is a member of the Rab family of small GTPases. In mouse, Rab23 has been shown to function as a negative regulator in the sonic hedgehog (Shh) signaling pathway. Rab23 mediates the activity of Gli2 and Gli3, transcription factors that regulate Shh signaling in the spinal cord, primarily by preventing Gli2 activation in the absence of Shh ligand. Rab23 also regulates a step in the cytoplasmic signal transduction pathway that mediates the effect of Smoothened (one of two integral membrane proteins that are essential components of the Shh signaling pathway in vertebrates). In humans, Rab23 is expressed in the retina. Mice contain an isoform that shares 93% sequence identity with the human Rab23 and an alternative splicing isoform that is specific to the brain. This isoform causes the murine open brain phenotype, indicating it may have a role in the development of the central nervous system. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state.

Rab3A, Rab3B, and Rab3C localized to synaptic and secretory vesicles; Rab3D was expressed at high levels only in adipose tissue, exocrine glands, and the endocrine pituitary, where it is localized to cytoplasmic secretory granules. Rab3 appears to control Ca2+-regulated exocytosis. The appropriate GDP/GTP exchange cycle of Rab3A is required for Ca2+-regulated exocytosis to occur, and interaction of the GTP-bound form of Rab3A with effector molecule(s) is widely believed to be essential for this process.

Rab GTPase family 18 (Rab18); Rab18 subfamily. Mammalian Rab18 is implicated in endocytic transport and is expressed most highly in polarized epithelial cells. However, trypanosomal Rab, TbRAB18, is upregulated in the BSF (Blood Stream Form) stage and localized predominantly to elements of the Golgi complex. In human and mouse cells, Rab18 has been identified in lipid droplets, organelles that store neutral lipids. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization. Most Rab GTPases contain a lipid modification site at the C-terminus, with sequence motifs CC, CXC, or CCX. Lipid binding is essential for membrane attachment, a key feature of most Rab proteins. Due to the presence of truncated sequences in this CD, the lipid modification site is not available for annotation. Pssm-ID: 206656 [Multi-domain] Cd Length: 161 Bit Score: 53.47 E-value: 3.04e-08

It interacts with some of the known Ras effectors, but appears to also have its own effectors. Expression of mutated M-Ras leads to transformation of several types of cell lines, including hematopoietic cells, mammary epithelial cells, and fibroblasts. Overexpression of M-Ras is observed in carcinomas from breast, uterus, thyroid, stomach, colon, kidney, lung, and rectum. In addition, expression of a constitutively active M-Ras mutant in murine bone marrow induces a malignant mast cell leukemia that is distinct from the monocytic leukemia induced by H-Ras. TC21, along with H-Ras, has been shown to regulate the branching morphogenesis of ureteric bud cell branching in mice.

Rab GTPase-like family 2 (Rab-like2); RabL2 (Rab-like2) subfamily. RabL2s are novel Rab proteins identified recently which display features that are distinct from other Rabs, and have been termed Rab-like. RabL2 contains RabL2a and RabL2b, two very similar Rab proteins that share > 98% sequence identity in humans. RabL2b maps to the subtelomeric region of chromosome 22q13.3 and RabL2a maps to 2q13, a region that suggests it is also a subtelomeric gene. Both genes are believed to be expressed ubiquitously, suggesting that RabL2s are the first example of duplicated genes in human proximal subtelomeric regions that are both expressed actively. Like other Rab-like proteins, RabL2s lack a prenylation site at the C-terminus. The specific functions of RabL2a and RabL2b remain unknown. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state.

Rab GTPase family 27a (Rab27a); The Rab27a subfamily consists of Rab27a and its highly homologous isoform, Rab27b. Unlike most Rab proteins whose functions remain poorly defined, Rab27a has many known functions. Rab27a has multiple effector proteins, and depending on which effector it binds, Rab27a has different functions as well as tissue distribution and/or cellular localization. Putative functions have been assigned to Rab27a when associated with the effector proteins Slp1, Slp2, Slp3, Slp4, Slp5, DmSlp, rabphilin, Dm/Ce-rabphilin, Slac2-a, Slac2-b, Slac2-c, Noc2, JFC1, and Munc13-4. Rab27a has been associated with several human diseases, including hemophagocytic syndrome (Griscelli syndrome or GS), Hermansky-Pudlak syndrome, and choroidermia. In the case of GS, a rare, autosomal recessive disease, a Rab27a mutation is directly responsible for the disorder. When Rab27a is localized to the secretory granules of pancreatic beta cells, it is believed to mediate glucose-stimulated insulin secretion, making it a potential target for diabetes therapy. When bound to JFC1 in prostate cells, Rab27a is believed to regulate the exocytosis of prostate- specific markers.

It is likely that these Rabs have functions that are specific to the mammalian lineage and have no orthologs in plants. Rab8 modulates polarized membrane transport through reorganization of actin and microtubules, induces the formation of new surface extensions, and has an important role in directed membrane transport to cell surfaces. The Ypt2 gene of the fission yeast Schizosaccharomyces pombe encodes a member of the Ypt/Rab family of small GTP-binding proteins, related in sequence to Sec4p of Saccharomyces cerevisiae but closer to mammalian Rab8.

Ral (Ras-like) family containing highly homologous RalA and RalB; The Ral (Ras-like) subfamily consists of the highly homologous RalA and RalB. Ral proteins are believed to play a crucial role in tumorigenesis, metastasis, endocytosis, and actin cytoskeleton dynamics. Despite their high sequence similarity (>80% sequence identity), nonoverlapping and opposing functions have been assigned to RalA and RalBs in tumor migration. In human bladder and prostate cancer cells, RalB promotes migration while RalA inhibits it. A Ral-specific set of GEFs has been identified that are activated by Ras binding. This RalGEF activity is enhanced by Ras binding to another of its target proteins, phosphatidylinositol 3-kinase (PI3K). Ral effectors include RLIP76/RalBP1, a Rac/cdc42 GAP, and the exocyst (Sec6/8) complex, a heterooctomeric protein complex that is involved in tethering vesicles to specific sites on the plasma membrane prior to exocytosis. In rat kidney cells, RalB is required for functional assembly of the exocyst and for localizing the exocyst to the leading edge of migrating cells. In human cancer cells, RalA is required to support anchorage-independent proliferation and RalB is required to suppress apoptosis. RalA has been shown to localize to the plasma membrane while RalB is localized to the intracellular vesicles. Most Ras proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid. Lipid binding is essential for membrane attachment, a key feature of most Ras proteins. Due to the presence of truncated sequences in this CD, the lipid modification site is not available for annotation. Pssm-ID: 206710 [Multi-domain] Cd Length: 163 Bit Score: 45.11 E-value: 2.14e-05

RSR1/Bud1p family GTPase; RSR1/Bud1p is a member of the Rap subfamily of the Ras family that is found in fungi. In budding yeasts, RSR1 is involved in selecting a site for bud growth on the cell cortex, which directs the establishment of cell polarization. The Rho family GTPase cdc42 and its GEF, cdc24, then establish an axis of polarized growth by organizing the actin cytoskeleton and secretory apparatus at the bud site. It is believed that cdc42 interacts directly with RSR1 in vivo. In filamentous fungi, polar growth occurs at the tips of hypha and at novel growth sites along the extending hypha. In Ashbya gossypii, RSR1 is a key regulator of hyphal growth, localizing at the tip region and regulating in apical polarization of the actin cytoskeleton. Most Ras proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid.

These proteins all lack a the C-terminal CaaX lipid-binding motif typical of Ras family proteins, and Rin and Ric contain calmodulin-binding domains. Rin, which is expressed only in neurons, induces neurite outgrowth in rat pheochromocytoma cells through its association with calmodulin and its activation of endogenous Rac/cdc42. Rit, which is ubiquitously expressed in mammals, inhibits growth-factor withdrawl-mediated apoptosis and induces neurite extension in pheochromocytoma cells. Rit and Rin are both able to form a ternary complex with PAR6, a cell polarity-regulating protein, and Rac/cdc42. This ternary complex is proposed to have physiological function in processes such as tumorigenesis. Activated Ric is likely to signal in parallel with the Ras pathway or stimulate the Ras pathway at some upstream point, and binding of calmodulin to Ric may negatively regulate Ric activity.

RERG expression was decreased or lost in a significant fraction of primary human breast tumors that lack estrogen receptor and are correlated with poor clinical prognosis. Elevated RERG expression correlated with favorable patient outcome in a breast tumor subtype that is positive for estrogen receptor expression. In contrast to most Ras proteins, RERG overexpression inhibited the growth of breast tumor cells in vitro and in vivo. RasL11 was found to be ubiquitously expressed in human tissue, but down-regulated in prostate tumors.

Rab GTPase family 28 (Rab28); Rab28 subfamily. First identified in maize, Rab28 has been shown to be a late embryogenesis-abundant (Lea) protein that is regulated by the plant hormone abcisic acid (ABA). In Arabidopsis, Rab28 is expressed during embryo development and is generally restricted to provascular tissues in mature embryos. Unlike maize Rab28, it is not ABA-inducible. Characterization of the human Rab28 homolog revealed two isoforms, which differ by a 95-base pair insertion, producing an alternative sequence for the 30 amino acids at the C-terminus. The two human isoforms are presumably the result of alternative splicing. Since they differ at the C-terminus but not in the GTP-binding region, they are predicted to be targeted to different cellular locations. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization. Most Rab GTPases contain a lipid modification site at the C-terminus, with sequence motifs CC, CXC, or CCX. Lipid binding is essential for membrane attachment, a key feature of most Rab proteins.

Rab GTPase family 9 (Rab9); Rab9 is found in late endosomes, together with mannose 6-phosphate receptors (MPRs) and the tail-interacting protein of 47 kD (TIP47). Rab9 is a key mediator of vesicular transport from late endosomes to the trans-Golgi network (TGN) by redirecting the MPRs. Rab9 has been identified as a key component for the replication of several viruses, including HIV1, Ebola, Marburg, and measles, making it a potential target for inhibiting a variety of viruses. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization. Most Rab GTPases contain a lipid modification site at the C-terminus, with sequence motifs CC, CXC, or CCX. Lipid binding is essential for membrane attachment, a key feature of most Rab proteins.

second BTB (Broad-Complex, Tramtrack and Bric a brac)/POZ (poxvirus and zinc finger) domain found in leucine-zipper-like transcriptional regulator 1 (LZTR-1); LZTR-1 is a golgi BTB-kelch protein that is degraded upon induction of apoptosis. It may also function as a transcriptional regulator that plays a crucial role in embryogenesis. Germline loss-of-function mutations in LZTR-1 predispose to an inherited disorder of multiple schwannomas. LZTR-1 contains two BTB domains. This model corresponds to the second domain. The BTB/POZ domain is a common protein-protein interaction motif of about 100 amino acids. Pssm-ID: 349618 [Multi-domain] Cd Length: 126 Bit Score: 37.37 E-value: 6.26e-03

BTB (Broad-Complex, Tramtrack and Bric a brac)/POZ (poxvirus and zinc finger) domain found in Drosophila melanogaster protein germ cell-less (GCL) and similar proteins; GCL proteins are nuclear envelope proteins highly conserved between the mammalian and Drosophila orthologs. Drosophila melanogaster GCL is a key regulator required for the specification of pole cells and primordial germ cell formation in embryos. Both, human germ cell-less protein-like 1 (GMCL1) and germ cell-less protein-like 2 (GMCL2), also called germ cell-less protein-like 1-like (GMCL1P1 or GMCL1L), may function in spermatogenesis. They may also be substrate-specific adaptors of E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. They contain BTB and BACK domains. The BTB/POZ domain is a common protein-protein interaction motif of about 100 amino acids.

BTB (Broad-Complex, Tramtrack and Bric a brac)/POZ (poxvirus and zinc finger) domain found in telomere zinc finger-associated protein (TZAP); TZAP is also called Krueppel-related zinc finger protein 3 (KR3), zinc finger and BTB domain-containing protein 48 (ZBTB48), or zinc finger protein 855 (ZNF855). It is a vertebrate telomere-binding protein involved in telomere length control. It directly binds the telomeric double-stranded 5'-TTAGGG-3' repeat. TZAP also acts as a transcription regulator that binds to promoter regions. It is a transcriptional activator of alternate reading frame (ARF) gene. It contains a BTB/POZ domain, a common protein-protein interaction motif of about 100 amino acids. Pssm-ID: 349541 [Multi-domain] Cd Length: 108 Bit Score: 36.66 E-value: 8.26e-03

BTB (Broad-Complex, Tramtrack and Bric a brac)/POZ (poxvirus and zinc finger) domain found in Kelch-like protein 11 (KLHL11); KLHL11 is a component of a cullin-RING-based BCR (BTB-CUL3-RBX1) E3 ubiquitin-protein ligase complex that mediates the ubiquitination of target proteins, leading most often to their proteasomal degradation. It contains a BTB domain and kelch repeats, characteristics of a kelch family protein. The BTB/POZ domain is a common protein-protein interaction motif of about 100 amino acids.
