Ubiquitin carboxyl-terminal hydrolase 10 (USP10)

Hydrolase that may remove conjugated ubiquitin from target proteins such as p53/TP53, BECN1, SNX3 and CFTR. Acts as an essential regulator of p53/TP53 stability: in unstressed cells, specifically deubiquitinates p53/TP53 in the cytoplasm, leading to counteract MDM2 activity and stabilize p53/TP53.

Following DNA damage, translocates into the nucleus and deubiquitinates p53/TP53, leading to modulate the p53/TP53-dependent DNA damage response. Component of a regulatory loop which controls autophagy and p53/TP53 amounts: mediates deubiquitination of BECN1, a key regulator of autophagy, leading to stabilize the PIK3C3/VPS34- containing complexes.
