Enables diacylglycerol diphosphate phosphatase activity; lipid phosphatase activity; and phosphatidate phosphatase activity. Involved in several processes, including phospholipid dephosphorylation; phospholipid metabolic process; and sphingolipid metabolic process. Located in caveola. Is expressed in several structures, including alimentary system; integumental system; nervous system; respiratory system; and sensory organ. Orthologous to human PLPP1 (phospholipid phosphatase 1).
