USP31 (Ubiquitin Specific Peptidase 31) is a Protein Coding gene. Among its related pathways are Ubiquitin-Proteasome Dependent Proteolysis. May recognize and hydrolyze the peptide bond at the C-terminal Gly of ubiquitin. Involved in the processing of poly-ubiquitin precursors as well as that of ubiquitinated proteins.
