RING finger, HC subclass, found in tripartite motif-containing protein 35 (TRIM35) and similar proteins; TRIM35, also known as hemopoietic lineage switch protein 5 (HLS5), is a putative hepatocellular carcinoma (HCC) suppressor that inhibits phosphorylation of pyruvate kinase isoform M2 (PKM2), which is involved in aerobic glycolysis of cancer cells and further suppresses the Warburg effect and tumorigenicity in HCC. It also negatively regulates Toll-like receptor 7 (TLR7)- and TLR9-mediated type I interferon production by suppressing the stability of interferon regulatory factor 7 (IRF7). Moreover, TRIM35 regulates erythroid differentiation by modulating globin transcription factor 1 (GATA-1) activity. TRIM35 belongs 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.

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.

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.

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-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.

PRY/SPRY domain of butyrophilin 3 (BTN3), includes BTN3A1, BTN3A2, BTN3A3 as well as BTN-like 3 (BTNL3); BTN3A also known as CD277; This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of butyrophilin family 3A (BTN3A); duplication events have led to three paralogs in primates: BTN3A1, BTN3A2, and BTN3A3. BTNs belong to receptor glycoproteins of immunoglobulin (Ig) superfamily, characterized by the presence of extracellular Ig-like domains (IgV and/or IgC). BTN3 transcripts are ubiquitously present in all immune cells (T cells, B cells, NK cells, monocytes, dendritic cells, and hematopoietic precursors) with different expression levels; BTN3A1 and BTN3A2 are expressed mainly by CD4+ and CD8+ T cells, BTN3A2 is the major form expressed in NK cells, and BTN3A3 is poorly expressed in these immune cells. The PRY/SPRY domain of the BTN3A1 isoform mediates phosphoantigen (pAg)-induced activation by binding directly to the pAg.

PRY/SPRY domain in tripartite motif-binding protein 21 (TRIM21) also known as 52kD Ribonucleoprotein Autoantigen (Ro52); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM21, which is also known as Sjogren Syndrome Antigen A (SSA), SSA1, 52kD Ribonucleoprotein Autoantigen (Ro52, Ro/SSA, SS-A/Ro) or RING finger protein 81 (RNF81). 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. It binds the Fc part of IgG molecules via its PRY-SPRY domain with unexpectedly high affinity.

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.

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.

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.

TRIM72 (also known as MG53) 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. It is expressed specifically in skeletal muscle and heart, and tethered to the plasma membrane and cytoplasmic vesicles via its interaction with phosphatidylserine. 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.
