PRY/SPRY domain in tripartite motif-containing protein 36 (TRIM36); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM36, a Class I TRIM protein. TRIM36 (also known as Haprin or RNF98) has a ubiquitin ligase activity and interacts with centromere protein-H, one of the kinetochore proteins. It has been shown that TRIM36 is potentially associated with chromosome segregation and that an excess of TRIM36 may cause chromosomal instability. In Xenopus laevis, TRIM36 is expressed during early embryogenesis and plays an important role in the arrangement of somites during their formation.

B-box-type 2 zinc finger found in tripartite motif-containing protein 36 (TRIM36) and similar proteins; TRIM36, human ortholog of mouse Haprin, also known as RING finger protein 98 (RNF98) or zinc-binding protein Rbcc728, is an E3 ubiquitin-protein ligase expressed in the germ plasm. It has been implicated in acrosome reaction, fertilization, and embryogenesis, as well as in carcinogenesis. TRIM36 functions upstream of Wnt/beta-catenin activation, and plays a role in controlling the stability of proteins regulating microtubule polymerization during cortical rotation, and subsequently dorsal axis formation. It is also potentially associated with chromosome segregation through interacting with the kinetochore protein centromere protein-H (CENP-H), and colocalizing with the microtubule protein alpha-tubulin. Its overexpression may cause chromosomal instability and carcinogenesis. It is, thus, a novel regulator affecting cell cycle progression. Moreover, TRIM36 plays a critical role in the arrangement of somites during embryogenesis. TRIM36 belongs to the C-I 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, Bbox1 and Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, a fibronectin type III (FN3) domain, and a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain. The type 2 B-box (Bbox2) zinc finger is characterized by a CHC3H2 zinc-binding consensus motif.

coiled-coil (CC) domain of Drosophila brain tumor (brat) and similar proteins; This family contains the coiled-coil (CC) region of Drosophila brain tumor (Brat), a translational repressor that belongs to the tripartite motif (TRIM) protein superfamily. TRIM proteins play important roles in various cellular processes and are involved in many diseases which consists of two B-box domains and a coiled-coil (CC) domain at the N-terminal region, and an NHL domain at the C-terminus. Brat localizes at the basal cortex during asymmetric division of Drosophila neuroblasts by directly interacting with the scaffolding protein Miranda (Mira), which it does through the CC-NHL domain tandem, indicating that the function of the Brat CC domain is to assemble Brat-NHL in dimeric form which is necessary for Mira binding. Brat CC forms an elongated antiparallel dimer similar to its other TRIM protein counterparts, but the overall length of Brat CC dimer is shorter than the TRIMs.

B-box-type 2 zinc finger found in midline (MID) family; The MID family includes MID1 and MID2. MID1, also known as midin, midline 1 RING finger protein, putative transcription factor XPRF, RING finger protein 59 (RNF59), or tripartite motif-containing protein 18 (TRIM18), is a microtubule-associated E3 ubiquitin-protein ligase implicated in epithelial-mesenchymal differentiation, cell migration and adhesion, and programmed cell death along specific regions of the ventral midline during embryogenesis. MID2, also known as midin-2, midline defect 2, RING finger protein 60 (RNF60), or tripartite motif-containing protein 1 (TRIM1), is highly related to MID1. It associates with the microtubule network and may at least partially compensate for the loss of MID1. Both MID1 and MID2 interacts with Alpha 4, which is a regulatory subunit of PP2-type phosphatases, such as PP2A, and an integral component of the rapamycin-sensitive signaling pathway. They also play a central role in the regulation of granule exocytosis, and functional redundancy exists between MID1 and MID2 in cytotoxic lymphocytes (CTL). Both MID1 and MID2 belong to the C-I 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, Bbox1 and Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, a fibronectin type III (FN3) domain, and a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain. The type 2 B-box (Bbox2) zinc finger is characterized by a CHC3H2 zinc-binding consensus motif.

B-box-type 2 zinc finger found in muscle-specific RING finger protein (MuRF) family; This family corresponds to a group of striated muscle-specific tripartite motif (TRIM) proteins, including TRIM63/MuRF-1, TRIM55/MuRF-2, and TRIM54/MuRF-3, which function as E3 ubiquitin ligases in ubiquitin-mediated muscle protein turnover. They are tightly developmentally regulated in skeletal muscle and associate with different cytoskeleton components, such as microtubules, Z-disks and M-bands, as well as with metabolic enzymes and nuclear proteins. They also cooperate with diverse proteins implicated in selective protein degradation by the proteasome and autophagosome, and target proteins of metabolic regulation, sarcomere assembly and transcriptional regulation. Moreover, MURFs display variable fibre-type preferences. TRIM63/MuRF-1 is predominantly fast (type II) fibre-associated in skeletal muscle. TRIM55/MuRF-2 is predominantly slow-fibre associated. TRIM54/MuRF-3 is ubiquitously present. They play an active role in microtubule-mediated sarcomere assembly. MuRFs belong to the C-II 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 COS (carboxyl-terminal subgroup one signature) box, and an acidic residue-rich (AR) domain positioned C-terminal to the RBCC domain. They also harbor a MURF family-specific conserved box (MFC) between its RING-HC finger and Bbox domains. The type 2 B-box (Bbox2) zinc finger is characterized by a CHC3H2 zinc-binding consensus motif.

TRIM C-terminal subgroup One Signature domain; This domain is found in the C-terminal region of the TRIM subgroup C-1 proteins such as E3 ubiquitin-protein ligase Midline-1 protein which is required for the proper development during embryogenesis. Mutations of MID1 are associated with X-linked Opitz G syndrome, characterized by midline anomalies. This domain is also found in MURF1-3 proteins that do not contain the FNIII and B30.2 domains. MUF1-3 proteins are also associated with microtubules. Deletion of the COS domain does not affect MID1 dimerization but disrupts the localization to the microtubules.

B-box-type 2 zinc finger found in muscle-specific RING finger protein 3 (MuRF-3) and similar proteins; MuRF-3, also known as tripartite motif-containing protein 54 (TRIM54), or RING finger protein 30 (RNF30), is an E3 ubiquitin-protein ligase in ubiquitin-mediated muscle protein turnover. It is ubiquitously detected in all fibre types, and is developmentally upregulated, associates with microtubules, the sarcomeric M-line and Z-line, and is required for microtubule stability and myogenesis. It associates with glutamylated microtubules during skeletal muscle development, and is required for skeletal myoblast differentiation and development of cellular microtubular networks. MuRF-3 controls the degradation of four-and-a-half LIM domain (FHL2) and gamma-filamin and is required for maintenance of ventricular integrity after myocardial infarction (MI). MuRF-3 belongs to the C-II 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 COS (carboxyl-terminal subgroup one signature) box, and an acidic residue-rich (AR) domain.

B-box-type 2 zinc finger found in tripartite motif-containing proteins, TRIM9, TRIM67 and similar proteins; This family includes a group of tripartite motif-containing proteins including TRIM9 and TRIM67, both of which belong to the C-I subclass of TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, consisting of three consecutive zinc-binding domains, a RING finger, Bbox1 and Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, a fibronectin type III (FN3) domain, and a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain. The type 2 B-box (Bbox2) zinc finger is characterized by a CHC3H2 zinc-binding consensus motif. TRIM9 (the human ortholog of rat Spring), also known as RING finger protein 91 (RNF91), is a brain-specific E3 ubiquitin-protein ligase collaborating with an E2 ubiquitin conjugating enzyme UBCH5b. It plays an important role in the regulation of neuronal functions and participates in neurodegenerative disorders through its ligase activity. TRIM67, also termed TRIM9-like protein (TNL), is a protein selectively expressed in the cerebellum. It interacts with PRG-1, an important molecule in the control of hippocampal excitability dependent on presynaptic LPA2 receptor signaling, and 80K-H (also known as glucosidase II beta), a protein kinase C substrate. It negatively regulates Ras signaling in cell proliferation via degradation of 80K-H, leading to neural differentiation including neuritogenesis.

B-box-type zinc finger superfamily; The B-box-type zinc finger is a short zinc binding domain of around 40 amino acid residues in length. It has been found in transcription factors, ribonucleoproteins and proto-oncoproteins, such as in TRIM (tripartite motif) proteins that consist of an N-terminal RING finger (originally called an A-box), followed by 1-2 B-box domains and a coiled-coil domain (also called RBCC for Ring, B-box, Coiled-Coil). The B-box-type zinc finger often presents in combination with other motifs, like RING zinc finger, NHL motif, coiled-coil or RFP domain in functionally unrelated proteins, most likely mediating protein-protein interactions. Based on different consensus sequences and the spacing of the 7-8 zinc-binding residues, B-box-type zinc fingers can be divided into two groups, type 1 (Bbox1: C6H2) and type 2 (Bbox2: CHC3H2).

B-box-type 1 zinc finger found in midline-1 (MID1) and similar proteins; MID1, also termed midin, or midline 1 RING finger protein, or putative transcription factor XPRF, or RING finger protein 59 (RNF59), or tripartite motif-containing protein 18 (TRI18), is a microtubule-associated E3 ubiquitin-protein ligase implicated in epithelial-mesenchymal differentiation, cell migration and adhesion, and programmed cell death along specific regions of the ventral midline during embryogenesis. It monoubiquinates the alpha4 subunit of protein phosphatase 2A (PP2A), promoting proteosomal degradation of the catalytic subunit of PP2A (PP2Ac) and preventing the A and B subunits from forming an active complex. It promotes allergen and rhinovirus-induced asthma through the inhibition of PP2A activity. It is strongly upregulated in cytotoxic lymphocytes (CTLs) and directs lytic granule exocytosis and cytotoxicity of killer T cells. Loss-of-function mutations in MID1 lead to the human X-linked Opitz G/BBB (XLOS) syndrome characterized by defective midline development during embryogenesis. MID1 belongs to the C-I 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, Bbox1 and Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, the fibronectin type III domain and the SPRY/B30.2 domain positioned C-terminal to the RBCC domain. The type 1 B-box (Bbox1) zinc finger is characterized by a C6H2 zinc-binding consensus motif. MID1 heterodimerizes in vitro with its paralog MID2.

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, 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.

B-box-type 1 zinc finger found in midline-2 (MID2) and similar proteins; MID2, also known as midin-2, midline defect 2, RING finger protein 60 (RNF60), or tripartite motif-containing protein 1 (TRIM1), is a probable E3 ubiquitin-protein ligase that is highly related to MID1, which associates with cytoplasmic microtubules along their length and throughout the cell cycle. Like MID1, MID2 associates with the microtubule network and may at least partially compensate for the loss of MID1. Both MID1 and MID2 interacts with alpha4, a regulatory subunit of PP2-type phosphatases, such as PP2A, and an integral component of the rapamycin-sensitive signaling pathway. MID2 can also substitute for MID1 to control exocytosis of lytic granules in cytotoxic T cells. Loss-of-function mutations in MID2 lead to human X-linked intellectual disability (XLID).

Normally, RIG-I is activated by TRIM25 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. However, RNF135, consisting of an N-terminal RING finger domain, C-terminal SPRY and PRY motifs and showing sequence similarity to TRIM25, acts as an alternative factor that promotes RIG-I activation independent of TRIM25.

B-box-type 2 zinc finger found in tripartite motif-containing protein TRIM2, TRIM3, and similar proteins; TRIM2, also known as RING finger protein 86 (RNF86), is an E3 ubiquitin-protein ligase that ubiquitinates the neurofilament light chain, a component of the intermediate filament in axons. Loss of function of TRIM2 results in early-onset axonal neuropathy. TRIM3, also known as brain-expressed RING finger protein (BERP), RING finger protein 97 (RNF97), or RING finger protein 22 (RNF22), is an E3 ubiquitin-protein ligase involved in the pathogenesis of various cancers. It also plays an important role in the central nervous system (CNS). In addition, TRIM3 may be involved in vesicular trafficking via its association with the cytoskeleton-associated-recycling or transport (CART) complex that is necessary for efficient transferrin receptor recycling, but not for epidermal growth factor receptor (EGFR) degradation. Both TRIM2 and TRIM3 belong to the C-VII subclass of TRIM (tripartite motif)-NHL family that is 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 domain, as well as a NHL (named after proteins NCL-1, HT2A and Lin-41 that contain repeats folded into a six-bladed beta propeller) repeat domain positioned C-terminal to the RBCC domain. 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.

B-box-type 1 zinc finger found in tripartite motif-containing protein 9 (TRIM9) and similar proteins; TRIM9 (the human ortholog of rat Spring), also termed RING finger protein 91 (RNF91), is a brain-specific E3 ubiquitin-protein ligase collaborating with an E2 ubiquitin conjugating enzyme UBCH5b. TRIM9 plays an important role in the regulation of neuronal functions and participates in neurodegenerative disorders through its ligase activity. It interacts with the WD repeat region of beta-transducer repeat-containing protein (beta-TCP) through its N-terminal degron motif depending on the phosphorylation status, and thus negatively regulate nuclear factor-kappaB (NF-kappaB) activation in the NF-kappaB pro-inflammatory signaling pathway. Moreover, TRIM9 acts as a critical catalytic link between Netrin-1 and exocytosis soluble NSF attachment receptor protein (SNARE) machinery in murine cortical neurons. It promotes SNARE-mediated vesicle fusion and axon branching in a Netrin-dependent manner. TRIM9 belongs to the C-I 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, Bbox1 and Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, the fibronectin type III domain and the SPRY/B30.2 domain positioned C-terminal to the RBCC domain. The type 1 B-box (Bbox1) zinc finger is characterized by a C6H2 zinc-binding consensus motif.

It has been implicated in cell proliferation, protein modification, and the retinoic acid inducible gene I (RIG-I)-mediated antiviral signaling pathway. It functions as an E3-ubiquitin ligase able to transfer ubiquitin and ISG15 to target proteins. TRIM47, also known as gene overexpressed in astrocytoma protein (GOA) or RING finger protein 100 (RNF100), plays an important role in the process of dedifferentiation that is associated with astrocytoma tumorigenesis.

B-box-type 2 zinc finger found in transcription intermediary factor 1-alpha (TIF1-alpha); TIF1-alpha, also known as tripartite motif-containing protein 24 (TRIM24), E3 ubiquitin-protein ligase TRIM24, or RING finger protein 82, belongs to the C-VI 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, Bbox1 and Bbox2, and a coiled coil region, as well as a plant homeodomain (PHD), and a bromodomain (Bromo) positioned C-terminal to the RBCC domain. The type 2 B-box (Bbox2) zinc finger is characterized by a CHC3H2 zinc-binding consensus motif. TIF1-alpha interacts specifically and in a ligand-dependent manner with the ligand binding domain (LBD) of several nuclear receptors (NRs), including retinoid X (RXR), retinoic acid (RAR), vitamin D3 (VDR), estrogen (ER), and progesterone (PR) receptors. It also associates with heterochromatin-associated factors HP1alpha, MOD1 (HP1beta), and MOD2 (HP1gamma), as well as the vertebrate Kruppel-type (C2H2) zinc finger proteins that contain the transcriptional silencing domain KRAB. TIF1-alpha is a ligand-dependent co-repressor of retinoic acid receptor (RAR) that interacts with multiple nuclear receptors in vitro via an LXXLL motif and further acts as a gatekeeper of liver carcinogenesis. It also functions as an E3-ubiquitin ligase targeting p53, and is broadly associated with chromatin silencing.

PRY/SPRY domain in tripartite motif-containing (TRIM) proteins, including TRIM14-like, TRIM16-like, TRIM25-like, TRIM47-like, TRIM65 and RNF135, and stonustoxin; 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 TRIM14, TRIM16 and TRIM25, TRIM47 as well as RING finger protein RNF135 and stonustoxin, a secreted poisonous protein of the stonefish Synanceja horrida. 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). 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 69 (TRIM69), also known as RING finger protein 36 (RNF36); This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM69, which is also known as RING finger protein 36 (RNF36) or testis-specific ring finger (Trif). TRIM69 domains are composed of RING/B-box/coiled-coil core and also known as RBCC proteins. It 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. The mouse ortholog of this gene is specifically expressed in germ cells at the round spermatid stages during spermatogenesis and, when overexpressed, induces apoptosis. TRIM69 has been shown to be a novel regulator of mitotic spindle assembly in tumor cells; it associates with spindle poles and promotes centrosomal clustering, and is therefore essential for formation of a bipolar spindle.
