Predicted to enable thiol-dependent deubiquitinase. Predicted to be involved in cell migration and photoreceptor cell maintenance. Predicted to act upstream of or within DNA repair and protein deubiquitination. Predicted to be located in cytoplasm; nucleus; and photoreceptor inner segment. Human ortholog(s) of this gene implicated in Leber congenital amaurosis. Orthologous to human USP45 (ubiquitin specific peptidase 45). [provided by Alliance of Genome Resources, Apr 2022]
