May form with the serine/threonine protein phosphatase l(1)G0269 an active complex dephosphorylating and activating lipin-like phosphatases. Lipins are phosphatidate phosphatases that catalyze the conversion of phosphatidic acid to diacylglycerol and control the metabolism of fatty acids at different levels (By similarity). Belongs to the CNEP1R1 family.
