Predicted to enable cysteine-type endopeptidase activity and thiol-dependent deubiquitinase. Involved in several processes, including protein deubiquitination; protein stabilization; and regulation of rRNA processing. Predicted to be located in cytoplasm; nuclear speck; and nucleolus. Predicted to be active in cytosol and nucleus. Orthologous to human USP36 (ubiquitin specific peptidase 36). [provided by Alliance of Genome Resources, Apr 2022]
