Predicted to enable Lys63-specific deubiquitinase activity and thiol-dependent deubiquitinase. Predicted to be involved in protein K63-linked deubiquitination. Predicted to act upstream of or within proteolysis. Predicted to be active in endosome and membrane. Is expressed in alimentary system; central nervous system; dorsal root ganglion; and limb. Orthologous to human STAMBPL1 (STAM binding protein like 1). [provided by Alliance of Genome Resources, Apr 2022]
