Acts as a key regulator of TGF-beta receptor signaling pathway, but the precise mechanism is still unclear: according to a report, acts by promoting deubiquitination of monoubiquitinated R-SMADs (SMAD1, SMAD2 and/or SMAD3), thereby alleviating inhibition of R-SMADs and promoting activation of TGF- beta target genes (PubMed:21947082). According to another reports, regulates the TGF-beta receptor signaling pathway by mediating deubiquitination and stabilization of TGFBR1, leading to an enhanced TGF-beta signal (PubMed:22344298). Able to mediate deubiquitination of monoubiquitinated substrates as well as 'Lys- 48'-linked polyubiquitin chains, protecting them against proteasomal degradation. May also regulate gene expression and/or DNA repair through the deubiquitination of histone H2B (PubMed:24526689). Acts as an inhibitor of mitophagy by counteracting the action of parkin (PRKN): hydrolyzes cleavage of 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains attached by parkin on target proteins such as MFN2, thereby reducing parkin's ability to drive mitophagy (PubMed:24852371). Acts as an associated component of COP9 signalosome complex (CSN) and regulates different pathways via this association: regulates NF- kappa-B by mediating deubiquitination of NFKBIA and deubiquitinates substrates bound to VCP (PubMed:16005295, PubMed:17318178, PubMed:19826004, PubMed:19576224). Involved in endosome organization by mediating deubiquitination of SQSTM1: ubiquitinated SQSTM1 forms a molecular bridge that restrains cognate vesicles in the perinuclear region and its deubiquitination releases target vesicles for fast transport into the cell periphery (PubMed:27368102). {ECO:0000269|PubMed:16005295, ECO:0000269|PubMed:17318178, ECO:0000269|PubMed:19576224, ECO:0000269|PubMed:19826004, ECO:0000269|PubMed:21947082, ECO:0000269|PubMed:22344298, ECO:0000269|PubMed:24526689, ECO:0000269|PubMed:24852371, ECO:0000269|PubMed:27368102}. |UCH| |DUSP| |ubiquitin modification-dependent histone binding| |histone H2B conserved C-terminal lysine deubiquitination| |monoubiquitinated protein deubiquitination| |pathway-restricted SMAD protein phosphorylation| |histone deubiquitination| |transforming growth factor beta receptor binding| |SMAD binding| |thiol-dependent ubiquitinyl hydrolase activity| |BMP signaling pathway| |cysteine-type endopeptidase activity| |transforming growth factor beta receptor signaling pathway| |response to BMP| |cellular response to BMP stimulus| |thiol-dependent ubiquitin-specific protease activity| |cellular response to transforming growth factor beta stimulus| |response to transforming growth factor beta| |transmembrane receptor protein serine/threonine kinase signaling pathway| |protein deubiquitination| |protein modification by small protein removal| |histone modification| |covalent chromatin modification| |cellular response to growth factor stimulus| |ubiquitin-dependent protein catabolic process| |response to growth factor| |modification-dependent protein catabolic process| |modification-dependent macromolecule catabolic process| |proteolysis involved in cellular protein catabolic process| |cellular protein catabolic process| |protein catabolic process| |chromatin organization| |enzyme linked receptor protein signaling pathway| |cellular macromolecule catabolic process| |protein phosphorylation| |protein modification by small protein conjugation or removal| |macromolecule catabolic process| |organonitrogen compound catabolic process| |chromosome organization| |identical protein binding| |cellular response to endogenous stimulus| |mitochondrion| |proteolysis| |phosphorylation| |response to endogenous stimulus| |organic substance catabolic process| |cellular catabolic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp31|Rifampicin 1μM R00 exp31]]|1.75| |[[:results:exp289|Hydroxyurea 15μM R06 exp289]]|1.8| |[[:results:exp503|Mitomycin-C 0.06μM R08 exp503]]|1.84| |[[:results:exp539|42°C R08 exp539]]|2.08| |[[:results:exp147|Resveratrol 16μM R03 exp147]]|2.12| |[[:results:exp290|LLY-283 2.6μM R06 exp290]]|2.19| |[[:results:exp36|TRAIL 50ng/ml R00 exp36]]|2.58| |[[:results:exp35|TRAIL 5ng/ml R00 exp35]]|2.6| |[[:results:exp19|Etoposide 1μM R00 exp19]]|2.74| No correlation found to any other genes in chemogenomics.
