Predicted to enable several functions, including BAT3 complex binding activity; chaperone binding activity; and cysteine-type peptidase activity. Predicted to be involved in several processes, including proteolysis; regulation of cellular catabolic process; and regulation of transcription, DNA-templated. Predicted to act upstream of or within protein K29-linked deubiquitination; protein K6-linked deubiquitination; and protein stabilization. Predicted to be active in cytosol and nucleus. Orthologous to human USP13 (ubiquitin specific peptidase 13). [provided by Alliance of Genome Resources, Apr 2022]
