Predicted to enable Lys48-specific deubiquitinase activity and thiol-dependent deubiquitinase. Predicted to act upstream of or within apoptotic process and proteolysis. Predicted to be located in nuclear membrane and nucleoplasm. Is expressed in cranial ganglion; dorsal root ganglion; heart; neural retina; and telencephalon. Orthologous to human MINDY3 (MINDY lysine 48 deubiquitinase 3). [provided by Alliance of Genome Resources, Apr 2022]
