FunctionUBP13_HUMAN Deubiquitinase that mediates deubiquitination of target proteins such as BECN1, MITF, SKP2 and USP10 and is involved in various processes such as autophagy and endoplasmic reticulum-associated degradation (ERAD).

Also deubiquitinates USP10, an essential regulator of p53/TP53 stability.
