SPRY domain; SPRY Domain is named from SPla and the RYanodine Receptor and it is found in many eukaryotic proteins with a wide range of functions. It is a protein-interaction module involved in many important signalling pathways like RNA processing, regulation of histone H3 methylation, innate immunity or embryonic development. It can be divided into 11 subfamilies based on amino acid sequence similarity or the presence of additional protein domains. The greater SPRY family is divided into the SPRY/B30.2 (which contains a PRY extension at the N-terminal) and SPRY-only sub-families which are preceded by a subdomain that is structurally similar to the PRY region. SPRY/B30.2 structures revealed a bent beta-sandwich fold comprised of two beta-sheets. Distant homologs are domains in butyrophilin/ marenostrin/pyrin.

PRY/SPRY domain in tripartite motif-containing (TRIM) proteins, including TRIM5, TRIM6, TRIM7, TRIM10, TRIM11, TRIM17, TRIM20, TRIM21, TRIM27, TRIM35, TRIM38, TRIM41, TRIM50, TRIM58, TRIM60, TRIM62, TRIM69, TRIM72, NF7 and bloodthirsty; This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of several Class IV TRIM proteins, including TRIM7, TRIM35, TRIM41, TRIM50, TRIM62, TRIM69, TRIM72, TRIM protein NF7 and bloodthirsty (bty). TRIM7 interacts with glycogenin and stimulates its self-glucosylating activity via its SPRY domain. TRIM35 may play a role as a tumor suppressor and is implicated in the cell death mechanism. TRIM41 is localized to speckles in the cytoplasm and nucleus, and functions as an E3 ligase that catalyzes the ubiquitin-mediated degradation of protein kinase C. TRIM50, an E3 ubiquitin ligase, is deleted in Williams-Beuren (WBS) syndrome, a multi-system neurodevelopmental disorder caused by the deletion of contiguous genes at chromosome region 7q11.23. TRIM62 is involved in the morphogenesis of the mammary gland; loss of TRIM62 gene expression in breast is associated with increased risk of recurrence in early-onset breast cancer. TRIM69 is a novel testis E3 ubiquitin ligase that may function to ubiquitinate its particular substrates during spermatogenesis. In humans, TRIM69 localizes in the cytoplasm and nucleus, and requires an intact RING finger domain to function. TRIM protein NF7, which also contains a chromodomain (CHD) at the N-terminus and an RFP (Ret finger protein)-like domain at the C-terminus, is required for its association with transcriptional units of RNA polymerase II which is mediated by a trimeric B box. In Xenopus oocyte, xNF7 has been identified as a nuclear microtubule-associated protein (MAP) whose microtubule-bundling activity, but not E3-ligase activity, contributes to microtubule organization and spindle integrity. Bloodthirsty (bty) is a novel gene identified in zebrafish and has been shown to likely play a role in in regulation of the terminal steps of erythropoiesis. TRIM72 has been shown to perform a critical function in membrane repair following acute muscle injury by nucleating the assembly of the repair machinery at injury sites. The PRY-SPRY domain in these TRIM families is suggested to serve as the target binding site. Pssm-ID: 293968 [Multi-domain] Cd Length: 174 Bit Score: 294.77 E-value: 9.92e-98

butyrophilin subfamily member A1 and A2 (BTN1A and BTN2A); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of butyrophilin family 1A and 2A (BTN1A and BTN2A). BTNs belong to receptor glycoproteins of immunoglobulin (Ig) superfamily, characterized by the presence of extracellular Ig-like domains (IgV and/or IgC). BTN1A plays a role in the secretion, formation and stabilization of milk fat globules. The B30.2 domain of BTN1A1 binds the enzyme xanthine oxidoreductase (XOR) in order to participate in milk fat globule secretion; this interaction may lead to the production of reactive oxygen species, which have immunomodulatory and antimicrobial functions. Duplication events have led to three paralogs of BTN2A in primates: BTN2A1, BTN2A2, and BTN2A3. In humans, only BTN2A1 has been functionally characterized; it has been detected on epithelial cells and leukocytes, and identified as a novel ligand of dendritic cell-specific ICAM-3 grabbing nonintegrin (DCSIGN), a C-type lectin receptor that acts as an internalization receptor for HIV-1, HCV, and other pathogens. BTN2A2 mRNA has been shown to be expressed in circulating human immune cells. Pssm-ID: 293991 [Multi-domain] Cd Length: 172 Bit Score: 277.96 E-value: 3.76e-91

PRY/SPRY domain in tripartite motif-binding protein 39 (TRIM39) and TRIM39-like; This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of pyrin, several tripartite motif-containing proteins (TRIMs), including E3 ubiquitin-protein ligase (TRIM21), RET finger protein (RFP)/tripartite motif protein 27 (TRIM27), as well as butyrophilin (Btns) and butyrophilin-like (Btnl) family members, with the exception of Btnl2. Btn and Btnl family members are novel regulators of immune responses, with many of the genes located within the MHC. They are implicated in T-cell inhibition and modulation of epithelial cell-T cell interactions. TRIM21 (also known as RO52, SSA1 or RNF81) is a major autoantigen in autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, and Sjorgen's syndrome. TRIM27 (also known as Ret finger protein, RFP or RNF76) negatively regulates CD4 T-cells by ubiquitinating and inhibiting the class II phosphatidylinositol 3 kinase C2beta (PI3K-C2beta), a kinase critical for KCa3.1 channel activation. The PRY/SPRY domain of Pyrin, which is mutated in familial Mediterranean fever patients, interacts with inflammasome components and inhibits proIL-1beta processing.

PRY/SPRY domain in tripartite motif-binding protein 20 (TRIM20), also known as pyrin; This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM20, which is also known as pyrin or marenostrin. Unlike TRIM domains that are composed of RING/B-box/coiled-coil core, the N-terminal RING domain in TRIM20 is exchanged by a PYRIN domain (PYD), a prime mediator of protein interactions necessary for apoptosis, inflammation and innate immune signaling pathway, and it also harbors a C-terminal B30.2 domain. Mutations in pyrin (TRIM20) are associated with familial Mediterranean fever (FMF), a recessively hereditary periodic fever syndrome, characterized by episodes of inflammation and fever. These mutations cluster in the C-terminal B30.2 domain and therefore it is assumed that pyrin plays a role in the innate immune system by possibly effecting caspase-1-dependent IL-1beta maturation.

PRY/SPRY domain in tripartite motif-binding protein 7 (TRIM7)-like, including TRIM7, TRIM10, TRIM15, TRIM26, TRIM39, TRIM41; This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of several tripartite motif-containing (TRIM) proteins, including TRIM7 (also referred to as glycogenin-interacting protein, RING finger protein 90 or RNF90), TRIM10, TRIM15, TRIM26, TRIM39 and TRIM41. TRIM7 or GNIP interacts with glycogenin and stimulates its self-glucosylating activity via its SPRY domain. TRIM10 (also known as hematopoietic RING finger 1 (HERF1) or TRIM10/HERF1) plays a key role in definitive erythroid development; downregulation of the Spi-1/PU.1 oncogene induces the expression of TRIM10/HERF1, a key factor required for terminal erythroid cell differentiation and survival. Antiviral activity of TRIM15 is dependent on the ability of its B-box to interact with the MLV Gag precursor protein; downregulation of TRIM15, along with TRIM11, enhances virus release suggesting that these proteins contribute to the endogenous restriction of retroviruses in cells. Tripartite motif-containing 26 (TRIM26) function is as yet unknown; however, since it is localized in the human histocompatibility complex (MHC) class I region, TRIM26 may play a role in immune response although studies show no association between TRIM26 polymorphisms and the risk of aspirin-exacerbated respiratory disease. TRIM39 is a MOAP-1 (Modulator of Apoptosis)-binding protein that stabilizes MOAP-1 through inhibition of its poly-ubiquitination process. TRIM41 (also known as RING finger-interacting protein with C kinase or RINCK) functions as an E3 ligase that catalyzes the ubiquitin-mediated degradation of protein kinase C.

In humans, RFPL transcripts can be detected at the onset of neurogenesis in differentiating human embryonic stem cells, and in the developing human neocortex. The human RFPL1, 2, 3 genes have a role in neocortex development. RFPL1 is a primate-specific target gene of Pax6, a key transcription factor for pancreas, eye and neocortex development; human RFPL1 decreases cell number through its RFPL-defining motif (RDM) and SPRY domains. The RFPL4 (also known as RFPL4A) gene encodes a putative E3 ubiquitin-protein ligase expressed in adult germ cells and interacts with oocyte proteins of the ubiquitin-proteasome degradation pathway.

PRY/SPRY domain of tripartite motif-binding protein 38 (TRIM38), also known as Ring finger protein 15 (RNF15); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM38, which is also known as RING finger protein 15 (RNF15) or RORET. TRIM38 domains are composed of RING/B-box/coiled-coil core and also known as RBCC proteins. TRIM38 has been shown to act as a suppressor in TOLL-like receptor (TLR)-mediated interferon (IFN)-beta induction by promoting degradation of TRAF6 and NAP1 through the ubiquitin-proteasome system. Another study has shown that TRIM38 may act as a novel negative regulator for TLR3-mediated IFN-beta signaling by targeting TRIF for degradation. TRIM38 has been identified as a critical negative regulator in TNFalpha- and IL-1beta-triggered activation of NF-kappaB and MAP Kinases (MAPKs); it causes degradation of two essential cellular components, TGFbeta-associated kinase 1 (TAK1)-associating chaperones 2 and 3 (TAB2/3). The degradation is promoted through a lysosomal-dependent pathway, which requires the C-terminal PRY-SPRY of TRIM38. Enterovirus 71 infection induces degradation of TRIM38, suggesting that TRIM38 may play a role in viral infections. Pssm-ID: 293987 [Multi-domain] Cd Length: 182 Bit Score: 209.52 E-value: 1.28e-64

TRIM11 domains are composed of RING/B-box/coiled-coil core and also known as RBCC proteins. It localizes to the nucleus and the cytoplasm; it is overexpressed in high-grade gliomas and promotes proliferation, invasion, migration and glial tumor growth. TRIM11 increases expression of dopamine beta-hydroxylase gene by interacting with the homeodomain transcription factor, PHOX2B, via the B30.2/SPRY domain, thus playing a potential role in the specification of noradrenergic (NA) neuron phenotype. It has also been shown that TRIM11 plays a critical role in the clearance of mutant PHOX2B, which causes congenital central hypoventilation syndrome, via the proteasome. TRIM11 binds a key component of the activator-mediated cofactor complex (ARC105), and destabilizes it, through the ubiquitin-proteasome system; ARC105 mediates chromatin-directed transcription activation and is a key regulatory factor for transforming growth factor beta (TGFbeta) signaling.

PRY/SPRY domain of tripartite motif-binding protein 60 (TRIM60) also known as RING finger protein 33 (RNF33); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM60, which is also known as RING finger protein 33 (RNF33) or 129 (RNF129). TRIM60 domains are composed of RING/B-box/coiled-coil core and also known as RBCC proteins. Based on its expression profile, RNF33 likely plays an important role in the spermatogenesis process, the development of the pre-implantation embryo, and in testicular functions; Rnf33 is temporally transcribed in the unfertilized egg and the pre-implantation embryo, and is permanently silenced before the blastocyst stage. Mice experiments have shown that RNF33 associates with the cytoplasmic motor proteins, kinesin-2 family members 3A (KIF3A) and 3B (KIF3B), suggesting possible contribution to cargo movement along the microtubule in the expressed sites.

PRY/SPRY domain in tripartite motif-containing protein 27 (TRIM27), also known as RING finger protein 76 (RNF76); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM27, also known as RING finger protein 76 (RNF76) or RET finger protein (RFP). TRIM27 domain is composed of RING/B-box/coiled-coil core and also known as RBCC proteins. It is highly expressed in the spleen, thymus and in cells of the hematopoietic compartment. TRIM27 exhibits either nuclear or cytosolic localization depending on the cell type. TRIM27 negatively regulates nucleotide-binding oligomerization domain containing 2 (NOD2)-mediated signaling by proteasomal degradation of NOD2, suggesting that TRIM27 could be a new target for therapeutic intervention in NOD2-associated diseases such as Crohn's. High expression of TRIM27 is observed in several human cancers, including breast and endometrial cancer, where elevated TRIM27 expression predicts poor prognosis. Also, TRIM27 forms an oncogenic fusion protein with Ret proto-oncogene. It is involved in different stages of spermatogenesis and its significant expression in male germ cells and seminomas, suggests that TRIM27 may be associated with the regulation of testicular germ cell proliferation and histological-type of germ cell tumors. TRIM27 could also be a predictive marker for chemoresistance in ovarian cancer patients. In the neurotoxin model of Parkinson's disease (PD), deficiency of TRIM27 decreases apoptosis and protects dopaminergic neurons, making TRIM27 an effective potential target during the treatment of PD.

zinc-binding protein A33-like; This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM69 and TRIM proteins NF7 and bloodthirsty (bty). TRIM69 is a novel testis E3 ubiquitin ligase that may function to ubiquitinate its particular substrates during spermatogenesis. In humans, TRIM69 localizes in the cytoplasm and nucleus, and requires an intact RING finger domain to function. TRIM protein NF7, which also contains a chromodomain (CHD) at the N-terminus and an RFP (Ret finger protein)-like domain at the C-terminus, is required for its association with transcriptional units of RNA polymerase II which is mediated by a trimeric B box. In Xenopus oocyte, xNF7 has been identified as a nuclear microtubule-associated protein (MAP) whose microtubule-bundling activity, but not E3-ligase activity, contributes to microtubule organization and spindle integrity. Bloodthirsty (bty) is a novel gene identified in zebrafish and has been shown to likely play a role in in regulation of the terminal steps of erythropoiesis.

TRIM21 domains are composed of RING/B-box/coiled-coil core and also known as RBCC proteins. As an E3 ligase, TRIM21 mediates target specificity in ubiquitination; it regulates type 1 interferon and proinflammatory cytokines via ubiquitination of interferon regulatory factors (IRFs). It is up-regulated at the site of autoimmune inflammation, such as cutaneous lupus lesions, indicating a central role in the tissue destructive inflammatory process. It interacts with auto-antigens in patients with Sjogren syndrome and systemic lupus erythematosus, a chronic systemic autoimmune disease characterized by the presence of autoantibodies against the protein component of the human intracellular ribonucleoprotein-RNA complexes and more specifically TRIM21, Ro60/TROVE2 and La/SSB proteins.

PRY/SPRY domain, also known as B30.2; This domain contains residues in the N-terminus that form a distinct PRY domain structure such that the B30.2 domain consists of PRY and SPRY subdomains. B30.2 domains comprise the C-terminus of three protein families: BTNs (receptor glycoproteins of immunoglobulin superfamily); several TRIM proteins (composed of RING/B-box/coiled-coil core); Stonutoxin (secreted poisonous protein of the stonefish Synanceia horrida). While SPRY domains are evolutionarily ancient, B30.2 domains are a more recent adaptation where the SPRY/PRY combination is a possible component of immune defense. Among the TRIM proteins, also known as the N-terminal RING finger/B-box/coiled coil (RBCC) family, only Classes I and II contain the B30.2 domain that has evolved under positive selection. Class I TRIM proteins include multiple members involved in antiviral immunity at various levels of interferon signaling cascade. Among the 75 human TRIMs, roughly half enhance immune response, which they do at multiple levels in signaling pathways. The PRY-SPRY domain in these TRIM families is suggested to serve as the target binding site. Pssm-ID: 293934 [Multi-domain] Cd Length: 168 Bit Score: 174.42 E-value: 1.52e-51

341-499 | 4.45e-41 | ||||
PRY/SPRY domain of tripartite motif-binding protein 5, 6, 22 and 34 (TRIM5, TRIM6, TRIM22 and TRIM34); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of very close paralogs, TRIM5, TRIM6, TRIM22 and TRIM34. These domains are composed of RING/B-box/coiled-coil core and are also known as RBCC proteins. They form a locus of four closely related TRIM genes within an olfactory receptor-rich region on chromosome 11 of the human genome. Genetic analysis of this locus indicates that these four genes have evolved by gene duplication from a common ancestral gene. All genes in the TRIM6/TRIM34/TRIM5/TRIM22 locus are type I interferon inducible, with TRIM5 and TRIM22 possessing antiviral properties. TRIM5 promotes innate immune signaling by activating the TAK1 kinase complex by cooperating with the heterodimeric E2, UBC13/UEV1A. It also stimulates NFkB and AP-1 signaling, and the transcription of inflammatory cytokines and chemokines, amplifying these activities upon retroviral infection. Interaction of its PRY-SPRY or cyclophilin domains with the retroviral capsid lattice stimulates the formation of a complementary lattice by TRIM5, with greatly increased TRIM5 E3 activity, and host cell signal transduction. TRIM6 is selectively expressed in embryonic stem (ES) cells and interacts with the proto-oncogene product Myc, maintaining the pluripotency of the ES cells. TRIM6, together with E2 Ubiquitin conjugase (UbE2K) and K48-linked poly-Ub chains, is critical for the IkappaB kinase epsilon (IKKepsilon) branch of type I interferon (IFN-I) signaling pathway and subsequent establishment of a protective antiviral response. TRIM22 plays an integral role in the host innate immune response to viruses; it has been shown to inhibit the replication of a number of viruses, including HIV-1, hepatitis B, and influenza A. Altered TRIM22 expression has also been associated with multiple sclerosis, cancer, and autoimmune disease. While the PRY-SPRY domain of TRIM5a provides specificity and the capsid recognition motif to retroviral restriction, TRIM34 binds HIV-1 capsid but does not restrict HIV-1 infection.

TRIM6 domain is composed of RING/B-box/coiled-coil core and also known as RBCC protein. TRIM22 is an interferon-induced protein, predominantly expressed in peripheral blood leukocytes, in lymphoid tissue such as spleen and thymus, and in the ovary.TRIM22 plays an integral role in the host innate immune response to viruses; it has been shown to inhibit the replication of a number of viruses, including HIV-1, hepatitis B, and influenza A. TRIM22 inhibits influenza A virus (IAV) infection by targeting the viral nucleoprotein for degradation; it represents a novel restriction factor up-regulated upon IAV infection that curtails its replicative capacity in epithelial cells. Altered TRIM22 expression has also been associated with multiple sclerosis, cancer, and autoimmune disease. A large number of high-risk non-synonymous (ns)SNPs have been identified in the highly polymorphic TRIM22 gene, most of which are located in the SPRY domain and could possibly alter critical regions of the SPRY structural and functional residues, including several sites that undergo post-translational modification. TRIM22 is a direct p53 target gene and inhibits the clonogenic growth of leukemic cells. Its expression in Wilms tumors is negatively associated with disease relapse. It is greatly under-expressed in breast cancer cells as compared to non-malignant cell lines; p53 dysfunction may be one of the mechanisms for its down-regulation.

TRIM16 (also known as estrogen-responsive B box protein or EBBP) has E3 ubiquitin ligase activity. It is a regulator of keratinocyte differentiation and a tumor suppressor in retinoid-sensitive neuroblastoma. TRIM25 (also called Efp) ubiquitinates the N terminus of the viral RNA receptor retinoic acid-inducible gene-I (RIG-I) in response to viral infection, leading to activation of the RIG-I signaling pathway, thus resulting in type I interferon production to limit viral replication. It has been shown that the influenza A virus targets TRIM25 and disables its antiviral function. TRIM47, also known as GOA (Gene overexpressed in astrocytoma protein) or RNF100 (RING finger protein 100), is highly expressed in kidney tubular cells, but low expressed in most tissue. It is overexpressed in astrocytoma tumor cells and plays an important role in the process of dedifferentiation that is associated with astrocytoma tumorigenesis. RNF135 ubiquitinates RIG-I (retinoic acid-inducible gene-I) to promote interferon-beta induction during the early phase of viral infection. Stonustoxin (STNX) is a hypotensive and lethal protein factor that also possesses other biological activities such as species-specific hemolysis (due to its ability to form pores in the cell membrane) and platelet aggregation, edema-induction, and endothelium-dependent vasorelaxation (mediated by the nitric oxide pathway and activation of potassium channels).

PRY/SPRY domain in tripartite motif-containing proteins 1, 9, 18, 36, 46, 67,76 (TRIM1, TRIM9, TRIM18, TRIM36, TRIM46, TRIM67, TRIM76); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of several Class I TRIM proteins, including TRIM1, TRIM9, TRIM18, TRIM36, TRIM46, TRIM67 and TRIM76. TRIM1 (also known as MID2) and its close homolog, TRIM18 (also known as MID1), both contain a B30.2-like domain at their C-terminus and a single fibronectin type III (FN3) motif between it and their N-terminal RBCC domain. Their coiled-coil motifs mediate both homo- and heterodimerization, a prerequisite for association of the rapamycin-sensitive PP2A regulatory subunit Alpha 4 with microtubules. Mutations in TRIM18 have shown to cause Opitz syndrome, a disorder causing congenital anomalies such as cleft lip and palate as well as heart defects. TRIM9 is expressed mainly in the cerebral cortex, and functions as an E3 ubiquitin ligase. Its immunoreactivity is severely decreased in affected brain areas in Parkinson's disease and dementia with Lewy bodies, possibly playing an important role in the regulation of neuronal function and participating in pathological process of Lewy body disease through its ligase. TRIM36 interacts with centromere protein-H, one of the kinetochore proteins and possibly associates with chromosome segregation; an excess of TRIM36 may cause chromosomal instability. TRIM46 has not yet been characterized. TRIM67 negatively regulates Ras activity via degradation of 80K-H, leading to neural differentiation, including neuritogenesis. TRIM76 (also known as cardiomyopathy-associated protein 5 or CMYA5) is a muscle-specific member of the TRIM superfamily, but lacks the RING domain. It is possibly involved in protein kinase A signaling as well as vesicular trafficking. It has also been implicated in Duchenne muscular dystrophy and cardiac disease. The PRY-SPRY domain in these TRIM families is suggested to serve as the target binding site. Pssm-ID: 293969 [Multi-domain] Cd Length: 166 Bit Score: 129.32 E-value: 7.60e-35

PRY/SPRY domain in tripartite motif-binding protein 5 (TRIM5), also known as RING finger protein 88 (RNF88); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM5 which is also known as RING finger protein 88 (RNF88) or TRIM5alpha (TRIM5a), an antiretroviral restriction factor and a retrovirus capsid sensor in immune signaling. TRIM5 domain is composed of RING/B-box/coiled-coil core and also known as RBCC protein. It blocks retrovirus infection soon after the virion core enters the cell cytoplasm by recognizing the capsid protein lattice that encases the viral genomic RNA; the SPRY domain provides the capsid recognition motif that dictates specificity to retroviral restriction. TRIM5a, an E3 ubiquitin ligase, promotes innate immune signaling by activating the TAK1 kinase complex by cooperating with the heterodimeric E2, UBC13/UEV1A. It also stimulates NFkB and AP-1 signaling, and the transcription of inflammatory cytokines and chemokines, and amplifies these activities upon retroviral infection. Interaction of its PRY-SPRY or cyclophilin domains with the retroviral capsid lattice stimulates the formation of a complementary lattice by TRIM5, with greatly increased TRIM5 E3 activity, and host cell signal transduction.

SPRY domain; SPRY Domain is named from SPla and the RYanodine Receptor and it is found in many eukaryotic proteins with a wide range of functions. It is a protein-interaction module involved in many important signalling pathways like RNA processing, regulation of histone H3 methylation, innate immunity or embryonic development. It can be divided into 11 subfamilies based on amino acid sequence similarity or the presence of additional protein domains. The greater SPRY family is divided into the SPRY/B30.2 (which contains a PRY extension at the N-terminal) and SPRY-only sub-families which are preceded by a subdomain that is structurally similar to the PRY region. SPRY/B30.2 structures revealed a bent beta-sandwich fold comprised of two beta-sheets. Distant homologs are domains in butyrophilin/ marenostrin/pyrin.

TRIM4 domain is composed of RING/B-box/coiled-coil core and also known as RBCC protein. It is a positive regulator of RIG-I-mediated interferon (IFN) induction. It regulates virus-induced IFN induction and cellular antiviral innate immunity by targeting RIG-I for K63-linked poly-ubiquitination. Over-expression of TRIM4 enhances virus-triggered activation of transcription factors IRF3 and NF-kappaB, as well as IFN-beta induction. Expression of TRIM4 differs significantly in Huntington's Disease (HD) neural cells when compared with wild-type controls, possibly impacting down-regulation of the Huntingtin (HTT) gene, which is involved in the regulation of diverse cellular activities that are impaired in Huntington's Disease (HD) cells.

B7-H3 is an important immune checkpoint member of the B7 family and shares homology with other B7 ligands such as programmed death ligand 1 (PD-L1). The B7 family molecules interact with CD28 on T-cells to provide co-stimulatory signals that regulate T-cell activation and T-helper cell differentiation. Although B7-H3 has been shown to have both co-stimulatory and co-inhibitory effects on T-cell responses, the most current studies describe B7-H3 as a T cell inhibitor that promotes tumor aggressiveness and proliferation. Moreover, B7-H3 is highly overexpressed on a wide range of human solid cancers and promotes tumor growth, metastasis, and drug resistance. Thus, B7-H3 expression in tumors often correlates with both negative prognosis and poor clinical outcome in cancer patients.

SPRY domains have been identified in at least 11 protein families, covering a wide range of functions, including regulation of cytokine signaling (SOCS), RNA metabolism (DDX1 and hnRNP), immunity to retroviruses (TRIM5alpha), intracellular calcium release (ryanodine receptors or RyR) and regulatory and developmental processes (HERC1 and Ash2L). B30.2 also contains residues in the N-terminus that form a distinct PRY domain structure; i.e. B30.2 domain consists of PRY and SPRY subdomains. B30.2 domains comprise the C-terminus of three protein families: BTNs (receptor glycoproteins of immunoglobulin superfamily); several TRIM proteins (composed of RING/B-box/coiled-coil or RBCC core); Stonutoxin (secreted poisonous protein of the stonefish Synanceia horrida). TRIM/RBCC proteins are involved in a variety of processes, including apoptosis, cell cycle regulation, cell growth, senescence, viral response, meiosis, cell differentiation, and vesicular transport. Genes belonging to this family are implicated in several human diseases that vary from cancer to rare genetic syndromes. The PRY-SPRY domain in these TRIM families is suggested to serve as the target binding site. While SPRY domains are evolutionarily ancient, B30.2 domains are a more recent adaptation where the SPRY/PRY combination is a possible component of immune defense.

The CAR acts as a type I membrane receptor for group B1-B6 coxsackie viruses and subgroup C adenoviruses. For instance, adenovirus interacts with the coxsackievirus and adenovirus receptor to enter epithelial airway cells. The CAR is also shown to be involved in physiological processes such as neuronal and heart development, epithelial tight junction integrity, and tumor suppression. The CAR is a component of the epithelial apical junction complex that may function as a homophilic cell adhesion molecule and is essential for tight junction integrity. The CAR is also involved in transepithelial migration of leukocytes through adhesive interactions with JAML a transmembrane protein of the plasma membrane of leukocytes. The interaction between both receptors also mediates the activation of gamma-delta T-cells, a subpopulation of T-cells residing in epithelia and involved in tissue homeostasis and repair. The CAR is composed of one V-set and one C2-set Ig module, a single transmembrane helix, and an intracellular domain. This group belongs to the V-set of IgSF domains, having A, B, E and D strands in one beta-sheet and A', G, F, C, C' and C" in the other Pssm-ID: 409552 Cd Length: 114 Bit Score: 46.68 E-value: 2.67e-06

Included in this group are the CSPGs aggrecan, versican, and neurocan. In CSPGs, this Ig-like domain is followed by hyaluronan (HA)-binding tandem repeats, and a C-terminal region with epidermal growth factor-like, lectin-like, and complement regulatory protein-like domains. Separating these N- and C-terminal regions is a nonhomologous glycosaminoglycan attachment region. In cartilage, aggrecan forms cartilage link protein stabilized aggregates with hyaluronan (HA). These aggregates contribute to the tissue's load bearing properties. Aggrecan and versican have a wide distribution in connective tissue and extracellular matrices. Neurocan is localized almost exclusively in nervous tissue. Aggregates having other CSPGs substituting for aggrecan may contribute to the structural integrity of many different tissues. There is considerable evidence that HA-binding CSPGs are involved in developmental processes in the central nervous system.

Immunoglobulin Variable (IgV) domain of T cell Immunoglobulin Domain and Mucin Domain 3 (Tim-3), and similar domains; The members here are composed of the immunoglobulin variable (IgV) domain of T cell immunoglobulin domain and mucin domain 3 (Tim-3; also known as Hepatitis A virus cellular receptor 2 (HAVcr-2) and Cluster of Differentiation 366 (CD366)) and similar proteins. TIM-3 is a checkpoint inhibitor in immune responses to tumors, as well as involved in chronic viral infections. Thus, Tim-3 has emerged as one of most promising immune checkpoint targets for cancer immunotherapy. Tim-3 is highly expressed on Th1 lymphocytes and CD11b(+) macrophages and is upregulated on activated T and myeloid cells. TIM-3 regulates macrophage, activation and inhibits Th1 mediated immune responses to promote immunological tolerance. There are three TIM family members in humans (TIM-1, TIM-3, and TIM-4) and eight members in mice (TIM-1 to TIM-8). The IgV domain of human TIM-3 has been shown to bind ligands such as carcinoembryonic antigen cell adhesion molecule 1 (CEACAM1), high mobility group protein B1 (HMGB1)and galectin-9 (GAL9). The binding of GAL9 to TIM-3 can negatively regulate Th1 immune response, enhance immune tolerance and inhibit anti#tumor immunity. Dysregulation of the TIM-3/GAL9 pathway is implicated in numerous chronic autoimmune diseases, such as multiple sclerosis and systemic lupus erythematosus.

Immunoglobulin variable domain (IgV) in Cluster of Differentiation (CD) 86; The members here are composed of the immunoglobulin variable region (IgV) in the Cluster of Differentiation (CD) 86). Glycoproteins B7-1 (also known as cluster of differentiation (CD) 80) and B7-2 (also known as CD86) are expressed on antigen-presenting cells and deliver the co-stimulatory signal through CD28 and CTLA-4 (also known as CD152) on T cells. signaling through CD28 augments the T-cell response, whereas CTLA-4 signaling attenuates it. The CTLA-4 and B7-2 monomers are both two-layer beta-sandwiches that display the chain topology characteristic of the immunoglobulin variable (V-type) domains present in antigen receptors. The front and back sheets of B7-2 are composed of AGFCC'C" and BED strands, respectively. Members of the IgV family are components of immunoglobulin (Ig) and T cell receptors. The basic structure of Ig molecules is a tetramer of two light chains and two heavy chains linked by disulfide bonds. In Ig, each chain is composed of one variable domain (IgV) and one or more constant domains (IgC); these names reflect the fact that the variability in sequences is higher in the variable domain than in the constant domain. Within the variable domain, there are regions of even more variability called the hypervariable or complementarity-determining regions (CDRs) which are responsible for antigen binding. A predominant feature of most Ig domains is the disulfide bridge connecting 2 beta-sheets with a tryptophan residue packed against the disulfide bond.

Immunoglobulin Variable (IgV) domain of Programmed death ligand 1 (PD-L1); The members here are composed of the immunoglobulin variable (IgV) domain of Programmed death ligand 1 (PD-L1; also known as Cluster of Differentiation 274 (CD274)). PD-L1 is a cell-surface ligand that competes with PD-L2 for binding to the immunosuppressive receptor programmed death-1 (PD-1). PD-1 is a member of the B7 family that plays an important role in negatively regulating immune responses upon interaction with its two ligands, PD-L1 or PD-L2. Like PD-L2, PD-L1 interacts with PD-1 and suppresses T cell proliferation and cytokine production. The PD-1 receptor is expressed on the surface of activated T cells, while PD-L1 is expressed on cancer cells. When PD-1 and PD-L1 bind together, they form a molecular shield protecting tumor cells from being destroyed by the immune system. Thus, inhibiting the binding of PD-L1 to PD-1 with an antibody leads to killing of tumor cells by T cells. PD-1 inhibitors (such as Pembrolizumab, Nivolumab, and Cemiplimab) and PD-L1 inhibitors (such as Atezolizumab, Avelumab, and Durvalumab ) are an emerging class of immunotherapy that stimulate lymphocytes against tumor cells.

Poliovirus (PV) binds to its cellular receptor (PVR/CD155) to initiate infection. CD155 is a membrane-anchored, single-span glycoprotein; its extracellular region has three Ig-like domains. There are four different isotypes of CD155 (referred to as alpha, beta, gamma, and delta), that result from alternate splicing of the CD155 mRNA, and have identical extracellular domains. CD155-beta and CD155-gamma are secreted; CD155-alpha and CD155-delta are membrane-bound and function as PV receptors. The virus recognition site is contained in the amino-terminal domain, D1. Having the virus attachment site on the receptor distal from the plasma membrane may be important for successful initiation of infection of cells by the virus. CD155 binds in the poliovirus "canyon" with a footprint similar to that of the intercellular adhesion molecule-1 receptor on human rhinoviruses. This group also includes the first Ig-like domain of nectin-1 (also known as poliovirus receptor related protein(PVRL)1; CD111), nectin-3 (also known as PVRL 3), nectin-4 (also known as PVRL4; LNIR receptor)and DNAX accessory molecule 1 (DNAM-1; CD226).

The N-terminal domain of CRIg (also known as Z39Ig and V-set and Ig domain-containing 4 (VSIG4) belongs to the IgV family of immunoglobulin-like domains while the C-terminal domain of CRIg belongs to the IgC family of immunoglobulin-like domains. Like all members of this family, the CRIg domain contains two beta-sheets: one composed of strands A', G, F, C, C' and C", and the other of strands B, E and D. The complement system is an important part of the innate immune system and is required for removal of pathogens from the bloodstream. After exposure to pathogens, the third component of the complement system, C3, is cleaved to C3b which, after recruitment of factor B, initiates formation of the alternative pathway convertases. CRIg, a complement receptor expressed on macrophages, binds to C3b and iC3b mediating phagocytosis of the particles. It is also a potent inhibitor of the alternative pathway convertases and a negative regulator of T cell activation. The Ig superfamily is a heterogenous group of proteins, built on a common fold comprised of a sandwich of two beta sheets. Members of this group are components of immunoglobulin, neuroglia, cell surface glycoproteins, such as, T-cell receptors, CD2, CD4, CD8, and membrane glycoproteins, such as, butyrophilin and chondroitin sulfate proteoglycan core protein.
