Predicted to enable cysteine-type endopeptidase activity and thiol-dependent deubiquitinase. Predicted to be involved in positive regulation of canonical Wnt signaling pathway and protein K48-linked deubiquitination. Predicted to act upstream of or within Wnt signaling pathway and proteolysis. Predicted to be active in cytosol and nucleus. Orthologous to human USP34 (ubiquitin specific peptidase 34).
