Predicted to enable cysteine-type endopeptidase activity and thiol-dependent deubiquitinase. Predicted to be involved in protein deubiquitination. Predicted to act upstream of or within proteolysis. Predicted to be located in several cellular components, including membrane raft; nucleoplasm; and postsynaptic membrane. Predicted to be active in cytosol and nucleus. Is expressed in several structures, including germ cell of testis; intestine; liver and biliary system; salivary gland; and thymus. Orthologous to human USP48 (ubiquitin specific peptidase 48).
