Predicted to enable phosphatase activity. Predicted to be involved in several processes, including chondroitin sulfate proteoglycan biosynthetic process; glycosaminoglycan biosynthetic process; and positive regulation of heparan sulfate proteoglycan biosynthetic process. Predicted to be located in membrane. Predicted to be integral component of membrane. Predicted to be active in Golgi apparatus. Is expressed in central nervous system; jaw; musculoskeletal system; and olfactory epithelium. Orthologous to human PXYLP1 (2-phosphoxylose phosphatase 1).
