PRY/SPRY domain in tripartite motif-binding protein 15 (TRIM15); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of tripartite motif-containing protein 15 (TRIM15), also referred to as RING finger protein 93 (RNF93) or Zinc finger protein B7 or 178 (ZNFB7 or ZNF178). TRIM15 domains are composed of RING/B-box/coiled-coil core and also known as RBCC proteins. The PRY and SPRY/B30.2 domains can function as immune defense components and in pathogen sensing. TRIM15 has been shown to regulate inflammatory and innate immune signaling, in addition to displaying antiviral activities. Down-regulation of TRIM15, as well as TRIM11, enhances virus release, suggesting that these proteins contribute to the endogenous restriction of retroviruses in cells. TRIM15 is also a regulatory component of focal adhesion turnover and cell migration.

B-box-type 2 zinc finger found in tripartite motif-containing proteins, TRIM10, TRIM15, TRIM26, TRIM31 and similar proteins; This family includes TRIM10, TRIM15, TRIM26 and TRIM31. TRIM10, also known as B30-RING finger protein (RFB30), RING finger protein 9 (RNF9), or hematopoietic RING finger 1 (HERF1), is a novel hematopoiesis-specific RING finger protein required for terminal differentiation of erythroid cells. TRIM15, also termed RING finger protein 93 (RNF93), or zinc finger protein 178 (ZNF178), or zinc finger protein B7 (ZNFB7), is a focal adhesion protein that regulates focal adhesion disassembly. It localizes to focal contacts in a myosin-II-independent manner by an interaction between its coiled-coil domain and the LD2 motif of paxillin. TRIM15 can also associate with coronin 1B, cortactin, filamin binding LIM protein1, and vasodilator-stimulated phosphoprotein, which are involved in actin cytoskeleton dynamics. As an additional component of the integrin adhesome, it regulates focal adhesion turnover and cell migration. TRIM26, also known as acid finger protein (AFP), RING finger protein 95 (RNF95), or zinc finger protein 173 (ZNF173), is an E3 ubiquitin-protein ligase that negatively regulates interferon-beta production and antiviral response through polyubiquitination and degradation of nuclear transcription factor IRF3. It functions as an important regulator for RNA virus-triggered innate immune response by bridging TBK1 to NEMO (NF-kappaB essential modulator, also known as IKKgamma) and mediating TBK1 activation. It also acts as a novel tumor suppressor of hepatocellular carcinoma by regulating cancer cell proliferation, colony forming ability, migration, and invasion. TRIM31 is an E3 ubiquitin-protein ligase that primarily localizes to the cytoplasm, but is also associated with the mitochondria. It can negatively regulate cell proliferation and may be a potential biomarker of gastric cancer as it is overexpressed from the early stage of gastric carcinogenesis. TRIM31 is downregulated in non-small cell lung cancer and serves as a potential tumor suppressor. It interacts with p52 (Shc) and inhibits Src-induced anchorage-independent growth. TRIM10, TRIM15 and TRIM26 belong to the C-IV subclass of TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a RING finger, Bbox2, and a coiled coil region, as well as a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain. TRIM31 belongs to the C-V subclass of TRIM family of proteins. The type 2 B-box (Bbox2) zinc finger is characterized by a CHC3H2 zinc-binding consensus motif.

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.

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.

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 10 (TRIM10) also known as hematopoietic RING finger 1 (HERF1); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM10, also known as RING finger protein 9 (RNF9) or hematopoietic RING finger 1 (HERF1). TRIM10 domain is composed of RING/B-box/coiled-coil core and also known as RBCC protein. TRIM10/HERF1 is predominantly expressed during definitive erythropoiesis and in embryonic liver, and minimally expressed in adult liver, kidney, and colon. It is critical for erythroid cell differentiation and its down-regulation leads to cell death; inhibition of TRIM10 expression blocks terminal erythroid differentiation, while its over-expression in erythroid cells induces beta-major globin expression and erythroid differentiation.

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.

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.

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.

TRIM7 or GNIP interacts with glycogenin and stimulates its self-glucosylating activity via its SPRY domain. The GNIP gene encodes at least four distinct isoforms of GNIP, of which three (GNIP1, GNIP2, and GNIP3) have the B30.2 domain.

B-box-type 2 zinc finger found in tripartite motif-containing proteins, TRIM10, TRIM15, TRIM26, TRIM31 and similar proteins; This family includes TRIM10, TRIM15, TRIM26 and TRIM31. TRIM10, also known as B30-RING finger protein (RFB30), RING finger protein 9 (RNF9), or hematopoietic RING finger 1 (HERF1), is a novel hematopoiesis-specific RING finger protein required for terminal differentiation of erythroid cells. TRIM15, also termed RING finger protein 93 (RNF93), or zinc finger protein 178 (ZNF178), or zinc finger protein B7 (ZNFB7), is a focal adhesion protein that regulates focal adhesion disassembly. It localizes to focal contacts in a myosin-II-independent manner by an interaction between its coiled-coil domain and the LD2 motif of paxillin. TRIM15 can also associate with coronin 1B, cortactin, filamin binding LIM protein1, and vasodilator-stimulated phosphoprotein, which are involved in actin cytoskeleton dynamics. As an additional component of the integrin adhesome, it regulates focal adhesion turnover and cell migration. TRIM26, also known as acid finger protein (AFP), RING finger protein 95 (RNF95), or zinc finger protein 173 (ZNF173), is an E3 ubiquitin-protein ligase that negatively regulates interferon-beta production and antiviral response through polyubiquitination and degradation of nuclear transcription factor IRF3. It functions as an important regulator for RNA virus-triggered innate immune response by bridging TBK1 to NEMO (NF-kappaB essential modulator, also known as IKKgamma) and mediating TBK1 activation. It also acts as a novel tumor suppressor of hepatocellular carcinoma by regulating cancer cell proliferation, colony forming ability, migration, and invasion. TRIM31 is an E3 ubiquitin-protein ligase that primarily localizes to the cytoplasm, but is also associated with the mitochondria. It can negatively regulate cell proliferation and may be a potential biomarker of gastric cancer as it is overexpressed from the early stage of gastric carcinogenesis. TRIM31 is downregulated in non-small cell lung cancer and serves as a potential tumor suppressor. It interacts with p52 (Shc) and inhibits Src-induced anchorage-independent growth. TRIM10, TRIM15 and TRIM26 belong to the C-IV subclass of TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a RING finger, Bbox2, and a coiled coil region, as well as a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain. TRIM31 belongs to the C-V subclass of TRIM family of proteins. The type 2 B-box (Bbox2) zinc finger is characterized by a CHC3H2 zinc-binding consensus motif.

PRY/SPRY domain of tripartite motif-binding protein 60 and 75 (TRIM60 and TRIM75); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM60 and TRIM75, both composed of RING/B-box/coiled-coil core and also known as RBCC proteins. TRIM60 domain is also known as RING finger protein 33 (RNF33) or 129 (RNF129). 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. TRIM75, also known as Gm794, has a single site of positive selection in its RING domain associated with E3 ubiquitin ligase activity. It has not been detectably expressed experimentally due to their constant turnover by the proteasome, and therefore not been characterized.

PRY/SPRY domain in tripartite motif-binding protein 50 (TRIM50); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM50. 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. It is specifically expressed in gastric parietal cells and may play an essential role in tubulovesicular dynamics. It also interacts with and increases the level of p62, a multifunctional adaptor protein that is implicated in various cellular processes such as the autophagy clearance of polyubiquitinated protein aggregates.

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.

RING finger, HC subclass, found in RING finger protein 39 (RNF39) and similar proteins; RNF39, also called protein HZFw, may play a role in prolonged long term-potentiation (LTP) maintenance. It is involved in the etiology of Behcet's disease (BD). It may also be involved in HIV-1 replication. RNF39 acts as an E3 ubiquitin ligase that inhibits retinoic acid-inducible gene-I (RIG-I)-like receptor (RLR) pathways by mediating K48-linked ubiquitination and proteasomal degradation of DDX3X (DEAD-box RNA helicase 3, X-linked). RNF39 contains a typical C3HC4-type RING-HC finger.

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.

RING finger, HC subclass, found in tripartite motif-containing proteins TRIM5, TRIM6, TRIM22, TRIM34 and similar proteins; TRIM5, TRIM6, TRIM22, and TRIM34, four closely related tripartite motif-containing proteins, belong to the C-IV subclass of the TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a C3HC4-type RING-HC finger, Bbox1 and Bbox2, and a coiled coil region, as well as a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain. TRIM5, also known as RING finger protein 88 (RNF88), is a capsid-specific restriction factor that prevents infection from non-host-adapted retroviruses in a species-specific manner by binding to and destabilizing the retroviral capsid lattice before reverse transcription is completed. Its retroviral restriction activity correlates with the ability to activate TAK1-dependent innate immune signaling. TRIM5 also acts as a pattern recognition receptor that activates innate immune signaling in response to the retroviral capsid lattice. Moreover, TRIM5 plays a role in regulating autophagy through activation of autophagy regulator BECN1 by causing its dissociation from its inhibitors BCL2 and TAB2. It also plays a role in autophagy by acting as a selective autophagy receptor which recognizes and targets HIV-1 capsid protein p24 for autophagic destruction. TRIM6, also known as RING finger protein 89 (RNF89), is an E3-ubiquitin ligase that cooperates with the E2-ubiquitin conjugase UbE2K to catalyze the synthesis of unanchored K48-linked polyubiquitin chains, and further stimulates the interferon-I kappa B kinase epsilon (IKKepsilon) kinase-mediated antiviral response. It also regulates the transcriptional activity of Myc during the maintenance of embryonic stem (ES) cell pluripotency, and may act as a novel regulator for Myc-mediated transcription in ES cells. TRIM22, also known as 50 kDa-stimulated trans-acting factor (Staf-50) or RING finger protein 94 (RNF94), is an E3 ubiquitin-protein ligase that 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 acts as a suppressor of basal HIV-1 long terminal repeat (LTR)-driven transcription by preventing the transcription factor specificity protein 1 (Sp1) binding to the HIV-1 promoter. It also controls FoxO4 activity and cell survival by directing Toll-like receptor 3 (TLR3)-stimulated cells toward type I interferon (IFN) type I gene induction or apoptosis. Moreover, TRIM22 can activate the noncanonical nuclear factor-kappaB (NF-kappaB) pathway by activating I kappa B kinase alpha (IKKalpha). It also regulates nucleotide binding oligomerization domain containing 2 (NOD2)-dependent activation of interferon-beta signaling and nuclear factor-kappaB. TRIM34, also known as interferon-responsive finger protein 1 or RING finger protein 21 (RNF21), may function as antiviral protein that contribute to the defense against retroviral infections.
