Ubiquitin Thioesterase Otubain-2; Otubain-2 is also called ubiquitin thioesterase OTUB2, deubiquitinating enzyme OTUB2, OTU domain-containing ubiquitin aldehyde-binding protein 2, or ubiquitin-specific-processing protease OTUB2. It is a deubiquitylase (DUB)/ubiquitin thioesterase (EC 3.4.19.12) that mediates the deubiquitination of 'Lys-11'-,'Lys-48'- and 'Lys-63'-linked polyubiquitin chains, with a preference for 'Lys-63'-linked polyubiquitin chains. OTUB2 plays a role in DNA double-strand break (DSB) response (DDR); it enhances RNF8-mediated ubiquitination in an early phase of the DDR and promotes faster DSB repair but suppresses homologous recombination. It also functions as a cancer stemness and metastasis-promoting factor that deubiquitinates and activates the transcriptional regulators YAP/TAZ, which play important roles in development, physiology, and tumorigenesis and are negatively controlled by the Hippo pathway. OTUB2 belongs to the OTU family of cysteine proteases that use a conserved cysteine, histidine, and an aspartate, as the catalytic triad. It is classified as a family C65 cysteine protease by MEROPS. : Pssm-ID: 438601 Cd Length: 222 Bit Score: 409.08 E-value: 1.29e-146

Peptidase C65 Otubain; This family of proteins conserved from plants to humans is a highly specific ubiquitin iso-peptidase that removes ubiquitin from proteins. The modification of cellular proteins by ubiquitin (Ub) is an important event that underlies protein stability and function in eukaryote being a dynamic and reversible process. Otubain carries several key conserved domains: (i) the OTU (ovarian tumour domain) in which there is an active cysteine protease triad (ii) a nuclear localization signal, (iii) a Ub interaction motif (UIM)-like motif phi-xx-A-xxxs-xx-Ac (where phi indicates an aromatic amino acid, x indicates any amino acid and Ac indicates an acidic amino acid), (iv) a Ub-associated (UBA)-like domain and (v) the LxxLL motif.

Ubiquitin Thioesterase Otubain-1; Otubain-1 is also called ubiquitin thioesterase OTUB1, deubiquitinating enzyme OTUB1, OTU domain-containing ubiquitin aldehyde-binding protein 1, or ubiquitin-specific-processing protease OTUB1. It is a deubiquitylase (DUB)/ubiquitin thioesterase (EC 3.4.19.12) that can specifically remove 'Lys-48'-linked conjugated ubiquitin from protein substrates. It is also capable of cleaving NEDD8 (neural-precursor-cell-expressed developmentally down-regulated 8), but not SUMO (small ubiquitin-related modifier) 1/2/3 and ISG15 (interferon-stimulated gene 15) conjugates. In addition, OTUB1 inhibits the DNA damage response independently of its catalytic activity by blocking ubiquitin transfer onto protein substrates via sequestration of E2 ubiquitin-conjugating enzymes. It also regulates many cancer-associated signaling pathways including MAPK, ERa, epithelial-mesenchymal transition (EMT), RHOa, mTORC1, FOXM1 and P53 to promote tumor cell survival, proliferation, invasiveness and therapeutic resistance. OTUB1 belongs to the OTU family of cysteine proteases that use a conserved cysteine, histidine, and an aspartate, as the catalytic triad. It is classified as a family C65 cysteine protease by MEROPS.

Arabidopsis thaliana Deubiquitinating enzyme OTU1 and similar plant proteins; This group contains plant otibain-like proteins including Oryza sativa Japonica group otubain-like deubiquitinase and Arabidopsis thaliana deubiquitinating enzyme OTU1 (AtOTU1), also called OVARIAN TUMOR DOMAIN-containing deubiquitinating enzyme 1 or OTU domain-containing protein 1. It is a deubiquitylase (DUB)/ubiquitin thioesterase (EC 3.4.19.12) that mediates the deubiquitination of protein substrates and may therefore play an important regulatory role at the level of protein turnover by preventing degradation. AtOTU1 shows a preference for Met-1 and 'Lys-48' over 'Lys-63'-linked ubiquitin tetramers as substrates. It belongs to the OTU family of cysteine proteases that use a conserved cysteine, histidine, and an aspartate, as the catalytic triad. It is classified as a family C65 cysteine protease by MEROPS.

OTU (ovarian tumor) domain family; The OTU family of cysteine proteases use a conserved cysteine and histidine, and in most cases an aspartate, as the catalytic triad. 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. Pssm-ID: 438581 [Multi-domain] Cd Length: 128 Bit Score: 42.81 E-value: 2.26e-05

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.
