Predicted to enable glycerol-3-phosphatase activity. Predicted to be involved in glycerol biosynthetic process. Predicted to be located in nucleus. Predicted to be active in cytoplasm. Is expressed in several structures, including embryonic/larval midgut; embryonic/larval midgut primordium; and larval muscle cell. Orthologous to human PGP (phosphoglycolate phosphatase) and PDXP (pyridoxal phosphatase).
