Protein attributes

Sequence length	246 AA.

Protein existence	Inferred from homology

General annotation (Comments)

Function	Serine/threonine protein phosphatase that may dephosphorylate and activate lipin-like phosphatases. Lipins are phosphatidate phosphatases that catalyze the conversion of phosphatidic acid to diacylglycerol and control the metabolism of fatty acids at differents levels. May indirectly modulate the lipid composition of nuclear and/or endoplasmic reticulum membranes and be required for proper nuclear membrane morphology and/or dynamics. May also indirectly regulate the production of lipid droplets and triacylglycerol By similarity.
Catalytic activity	A phosphoprotein + H2O = a protein + phosphate.
Subcellular location	Membrane; Single-pass membrane protein Potential.
Sequence similarities	Belongs to the dullard family. Contains 1 FCP1 homology domain.
