Predicted to enable cysteine-type endopeptidase activity; protein kinase binding activity; and thiol-dependent deubiquitinase. Predicted to be involved in G1/S transition of mitotic cell cycle; protein deubiquitination; and regulation of DNA replication. Predicted to act upstream of or within cell division. Predicted to be active in cytosol and nucleus. Orthologous to human USP37 (ubiquitin specific peptidase 37). [provided by Alliance of Genome Resources, Apr 2022]
