OTU (ovarian tumor) domain of deubiquitinating enzyme OTU1 and OTU2 from plants and similar proteins; Deubiquitinating enzyme OTU2, also called OTU domain-containing protein 2, 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. OTU2 exhibited equivalent binding affinities for K48- and K63-linked ubiquitin chains and no cleavage activity toward linear UB chains. It may also be involved in endoplasmic-reticulum-associated protein degradation (ERAD). OTU2 belongs to the OTU family of cysteine proteases that use a conserved cysteine, histidine, and an aspartate, as the catalytic triad. : Pssm-ID: 438614 Cd Length: 163 Bit Score: 308.49 E-value: 1.24e-108

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.

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. OTU7 is a DUB that shows a preference for 'Lys-63' over 'Lys-48' over 'Met-1'-linked ubiquitin (UB) tetramers as substrates.

OTU (ovarian tumor) domain of Arabidopsis thaliana deubiquitinating enzyme OTU7 and similar proteins; Arabidopsis thaliana deubiquitinating enzyme OTU7, also called OTU domain-containing protein 7, is a deubiquitinase (DUB)/ubiquitin thioesterase (EC 3.4.19.12) that shows a preference for 'Lys-63' over 'Lys-48' over 'Met-1'-linked ubiquitin (UB) tetramers as substrates. DUBs 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. OTU7 belongs to the OTU family of cysteine proteases that use a conserved cysteine, histidine, and an aspartate, as the catalytic triad.

OTU-like cysteine protease; This family is comprised of a group of predicted cysteine proteases, homologous to the Ovarian Tumour (OTU) gene in Drosophila. Members include proteins from eukaryotes, viruses and pathogenic bacterium. The conserved cysteine and histidine, and possibly the aspartate, represent the catalytic residues in this putative group of proteases.

OTU (ovarian tumor) domain of the potexviruses/carlaviruses RNA replication protein family; RNA replication polyprotein (RDRP) is a viral homolog of ovarian tumor protease (vOTU), which displays RNA helicase (EC 3.6.4.13), RNA-directed RNA polymerase (EC 2.7.7.48), viral methyltransferase, Fe(2+) 2-oxoglutarate dioxygenase and protease activities. The central part of this protein possibly functions as an ATP-binding helicase. It is an RNA-directed RNA polymerase involved in viral RNA replication. It also acts as a thiol protease that cleaves the polyprotein. This subfamily belongs to the OTU family of cysteine proteases that use a conserved cysteine, histidine, and an aspartate, as the catalytic triad.
