Enables hydrolase activity, hydrolyzing N-glycosyl compounds and mannosidase activity. Predicted to be involved in N-glycan processing and protein deglycosylation. Predicted to be located in Golgi apparatus and membrane. Predicted to be integral component of membrane. Predicted to be active in Golgi membrane. Is expressed in olfactory epithelium; retina outer nuclear layer; skeletal muscle; and vomeronasal organ. Orthologous to human MAN2A2 (mannosidase alpha class 2A member 2).
