Predicted to enable calcium ion binding activity and mannosyl-oligosaccharide 1,2-alpha-mannosidase activity. Predicted to be involved in ERAD pathway. Predicted to act upstream of or within mannose metabolic process and proteoglycan biosynthetic process. Predicted to be located in Golgi apparatus. Predicted to be active in Golgi membrane and endoplasmic reticulum. Is expressed in several structures, including cerebellum; genitourinary system; gut; hemolymphoid system gland; and liver. Orthologous to human MAN1C1 (mannosidase alpha class 1C member 1).
