OTU (ovarian tumor) domain of deubiquitinating enzyme OTU6 from plants and similar proteins; Deubiquitinating enzyme OTU6, also called OTU domain-containing protein 6 or otubain-like deubiquitinase 1 (OTLD1), is a deubiquitinase (DUB) or ubiquitin thiolesterase (EC 3.4.19.12) that catalyzes the thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin, a small regulatory protein that can be conjugated to a large range of target proteins. Protein ubiquitination is a post-translational modification of mostly Lys residues that regulates many cellular processes, including protein degradation, intracellular trafficking, cell signaling, autophagy, transcription, translation, and the DNA damage response. OTU6 binds chromatin and has enzymatic histone deubiquitinase activity specific for the H2B histone. OTU6 belongs to the OTU family of cysteine proteases that use a conserved cysteine, histidine, and an aspartate, as the catalytic triad.

OTU (ovarian tumor) domain of OTU domain-containing proteins 6A, 6B, and similar proteins; This subfamily is composed of mammalian OTU domain-containing protein 6A (OTUD6A, also called DUBA-2, vertebrate OTU domain-containing protein 6B (OTUD6B, also called DUBA-5), fungal OTU domain-containing protein 2 (OTU2), and similar proteins. OTUD6A, OTUD6B, and Schizosaccharomyces pombe OTU2 are deubiquitinating enzymes/ubiquitinyl hydrolases (EC 3.4.19.12). OTUD6A hydrolyzes 'Lys-27'-, 'Lys-29'-, and 'Lys-33'-linked polyubiquitin chains, and may also be able to hydrolyze 'Lys-11'-linked ubiquitin chains. It deubiquitylates and stabilizes dynamin-related protein 1 (Drp1), a cytosolic protein responsible for mitochondrial fission and is essential in the initiation and development of several human diseases including cancer, thereby facilitating tumorigenesis. OTUD6B is a functional deubiquitinase in in vitro enzyme assays. It may play a role in the ubiquitin-dependent regulation of protein synthesis downstream of mTORC1, and may modify the ubiquitination of the protein synthesis initiation complex to repress translation. Biallelic variants in OTUD6B cause an intellectual disability syndrome that is associated with seizures and dysmorphic features. This subfamily belongs to the OTU family of cysteine proteases that use a conserved cysteine, histidine, and an aspartate, as the catalytic triad.

OTU (ovarian tumor) domain of bifunctional UDP-N-acetylglucosamine transferase and deubiquitinase ALG13 and similar proteins; Bifunctional UDP-N-acetylglucosamine transferase and deubiquitinase ALG13 is alco called asparagine-linked glycosylation 13 homolog, glycosyltransferase 28 domain-containing protein 1 (GLT28D1), or UDP-N-acetylglucosamine transferase subunit ALG13 homolog. It displays both glycosyltransferase (EC 2.4.1.141) and deubiquitinase (DUB)/ubiquitin thioesterase (EC 3.4.19.12) activities. With ALG14, it forms a UDP-N-acetylglucosamine transferase that catalyzes the second step of eukaryotic N-linked glycosylation in the endoplasmic reticulum. ALG13 variants cause a form of early infantile epileptic encephalopathy known as EIEE36 refractory seizures, neurodevelopmental impairment, and poor prognosis; given the essential role of ALG13 in glycosylation, it is also considered a congenital disorder of glycosylation (CDG). This subfamily also contains OTU domain-containing protein 4 (OTUD4), also called HIV-1-induced protein HIN-1, a DUB that specifically deubiquitinates 'Lys-63'-polyubiquitinated MYD88 adapter protein upon phosphorylation, triggering down-regulation of NF-kappa-B-dependent transcription of inflammatory mediators. This subfamily belongs to the OTU family of cysteine proteases that use a conserved cysteine, histidine, and an aspartate, as the catalytic triad.

OTU (ovarian tumor) domain of nucleopolyhedrovirus P87/VP80 protein and similar proteins; The VP80 protein is a capsid-associated structural protein that was first identified as P87 in Orgyia pseudotsugata multicapsid nuclear polyhedrosis virus (OpMNPV); its homologs are found only in NPV genomes. The Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV) VP80 protein is essential for the formation of both budded virus (BV) and occlusion-derived virus (ODV). It has also been shown to interact with the virus-triggered, nuclear F-actin cytoskeleton. P87/VP80 contains an N-terminal OTU domain. OTU domains typically function as deubiquitinases (DUBs)/ubiquitin thiolesterases (EC 3.4.19.12) that catalyze the thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin, a small regulatory protein that can be conjugated to a large range of target proteins. Protein ubiquitination is a post-translational modification of mostly Lys residues that regulates many cellular processes, including protein degradation, intracellular trafficking, cell signaling, autophagy, transcription, translation, and the DNA damage response. These DUBs may play important regulatory roles at the level of protein turnover by preventing degradation.

OTU (ovarian tumor) domain of OTU domain-containing protein 3 and similar proteins; OTU domain-containing protein 3 (OTUD3) is a deubiquitinase (DUB)/ubiquitin thioesterase (EC 3.4.19.12) that hydrolyzes 'Lys-6'- and 'Lys-11'-linked polyubiquitin. It is an acetylation-dependent deubiquitinase that restricts innate antiviral immune signaling. It directly hydrolyzes lysine 63 (Lys63)-linked polyubiquitination of MAVS (mitochondrial antiviral-signaling protein) and shuts off innate antiviral immune response. OTUD3 can elicit tumor-suppressing or tumor-promoting activities in a cell- and tissue-dependent manner. It is a DUB for PTEN (phosphatase and tension homologue deleted on chromosome 10); the OTUD3-PTEN signaling axis plays a critical role in suppression of breast tumorigenesis. OTUD3 is also a DUB for glucose-regulated protein GRP78, stabilizing it and promoting lung tumorigenesis. It belongs to the OTU family of cysteine proteases that use a conserved cysteine, histidine, and an aspartate, as the catalytic triad.

Protein ubiquitination is a post-translational modification of mostly Lys residues that regulates many cellular processes, including protein degradation, intracellular trafficking, cell signaling, autophagy, transcription, translation, and the DNA damage response. OTU5 is an inactive cysteine protease. It regulates gene expression by contributing to chromatin organization and DNA methylation patterns (e.g. H3K4me3 and H3K27me3). It is required for phosphate (Pi) homeostasis. OTU5 belongs to the OTU family of cysteine proteases that use a conserved cysteine, histidine, and an aspartate, as the catalytic triad.

OTU (ovarian tumor) domain of ubiquitin thioesterase OTU1 and similar proteins; Ubiquitin thioesterase (EC 3.4.19.12) OTU1 is also called OTU domain-containing protein 1 in yeast, while human OTU1 is also called HIV-1-induced protease 7 (HIN7), DUBA-8, or OTU domain-containing protein 2 (OTUD2). OTU1 is a deubiquitinase (DUB) that catalyzes the thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin, a small regulatory protein that can be conjugated to a large range of target proteins. Protein ubiquitination is a post-translational modification of mostly Lys residues that regulates many cellular processes, including protein degradation, intracellular trafficking, cell signaling, autophagy, transcription, translation, and the DNA damage response. OTU1 has been implicated in the ER-associated degradation (ERAD) pathway. In yeast, it counteracts the activity of Ufd2 by deubiquitinating Ufd2 substrates; Ufd2 is a E4 ubiquitin ligase that interacts with Cdc48, an AAA ATPase that plays a central role in the ERAD pathway by chaperoning proteins to the proteasome for destruction. OTU1 also functions as a substrate-processing factor of valosin-containing protein (VCP, the mammalian counterpart of yeast Cdc48) that is required for the retrotranslocation of the ERAD pathway. OTU1 has been shown to preferentially hydrolyze polyubiquitin chains with Lys48 linkages. It contains ubiquitin-like (Ubl) domain with a beta-grasp Ubl fold, a C2H2-type zinc finger, and an OTU (ovarian tumor) domain. This model represents the OTU domain that interacts with ubiquitin and possesses catalytic activity. OTU1 belongs to the OTU family of cysteine proteases that use a conserved cysteine, histidine, and an aspartate, as the catalytic triad. This family also contains plant OTU1 and OTU2.

OTU (ovarian tumor) domain of vertnin and similar proteins; Vertnin (VRTN) is an OTU domain-containing protein that is required for the development of thoracic vertebrae in mammals. OTU domains typically function as deubiquitinases (DUBs)/ubiquitin thiolesterases (EC 3.4.19.12) that catalyze the thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin, a small regulatory protein that can be conjugated to a large range of target proteins. Protein ubiquitination is a post-translational modification of mostly Lys residues that regulates many cellular processes, including protein degradation, intracellular trafficking, cell signaling, autophagy, transcription, translation, and the DNA damage response. These DUBs may play important regulatory roles at the level of protein turnover by preventing degradation. Vertnin and some subfamily members do not possess the conserved catalytic residues and may not have DUB activity. VRTN gene is associated with variations in vertebral number.
