Anti-USP10 antibody

타겟 정보

Hydrolase that can remove conjugated ubiquitin from target proteins such as p53/TP53, RPS2/us5, RPS3/us3, RPS10/eS10, BECN1, SNX3 and CFTR (PubMed : 11439350, PubMed : 18632802, PubMed : 31981475). Acts as an essential regulator of p53/TP53 stability : in unstressed cells, specifically deubiquitinates p53/TP53 in the cytoplasm, leading to counteract MDM2 action and stabilize p53/TP53 (PubMed : 20096447). Following DNA damage, translocates to the nucleus and deubiquitinates p53/TP53, leading to regulate the p53/TP53-dependent DNA damage response (PubMed : 20096447). Component of a regulatory loop that controls autophagy and p53/TP53 levels : mediates deubiquitination of BECN1, a key regulator of autophagy, leading to stabilize the PIK3C3/VPS34-containing complexes (PubMed : 21962518). In turn, PIK3C3/VPS34-containing complexes regulate USP10 stability, suggesting the existence of a regulatory system by which PIK3C3/VPS34-containing complexes regulate p53/TP53 protein levels via USP10 and USP13 (PubMed : 21962518). Does not deubiquitinate MDM2 (PubMed : 20096447). Plays a key role in 40S ribosome subunit recycling when a ribosome has stalled during translation : acts both by inhibiting formation of stress granules, which store stalled translation pre-initiation complexes, and mediating deubiquitination of 40S ribosome subunits (PubMed : 27022092, PubMed : 31981475, PubMed : 34348161, PubMed : 34469731). Acts as a negative regulator of stress granules formation by lowering G3BP1 and G3BP2 valence, thereby preventing G3BP1 and G3BP2 ability to undergo liquid-liquid phase separation (LLPS) and assembly of stress granules (PubMed : 11439350, PubMed : 27022092, PubMed : 32302570). Promotes 40S ribosome subunit recycling following ribosome dissociation in response to ribosome stalling by mediating deubiquitination of 40S ribosomal proteins RPS2/us5, RPS3/us3 and RPS10/eS10, thereby preventing their degradation by the proteasome (PubMed : 31981475, PubMed : 34348161, PubMed : 34469731). Part of a ribosome quality control that takes place when ribosomes have stalled during translation initiation (iRQC) : USP10 acts by removing monoubiquitination of RPS2/us5 and RPS3/us3, promoting 40S ribosomal subunit recycling (PubMed : 34469731). Deubiquitinates CFTR in early endosomes, enhancing its endocytic recycling (PubMed : 19398555). Involved in a TANK-dependent negative feedback response to attenuate NF-kappa-B activation via deubiquitinating IKBKG or TRAF6 in response to interleukin-1-beta (IL1B) stimulation or upon DNA damage (PubMed : 25861989). Deubiquitinates TBX21 leading to its stabilization (PubMed : 24845384). Plays a negative role in the RLR signaling pathway upon RNA virus infection by blocking the RIGI-mediated MAVS activation. Mechanistically, removes the unanchored 'Lys-63'-linked polyubiquitin chains of MAVS to inhibit its aggregation, essential for its activation (PubMed : 37582970).
