Predicted to enable cysteine-type endopeptidase activity and thiol-dependent deubiquitinase. Predicted to be involved in G1/S transition of mitotic cell cycle and protein deubiquitination. Predicted to act upstream of or within proteolysis. Predicted to be active in cytosol and nucleus. Is expressed in several structures, including brain; limb bud; testis; and trunk. Orthologous to human USP29 (ubiquitin specific peptidase 29). [provided by Alliance of Genome Resources, Apr 2022]
