Protein attributes

Sequence length	245 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Serine/threonine protein phosphatase that may dephosphorylate and activate lipins. 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. May antagonize BMP signaling By similarity.
Catalytic activity	A phosphoprotein + H2O = a protein + phosphate.
Subcellular location	Endoplasmic reticulum membrane; Single-pass membrane protein By similarity. Nucleus membrane; Single-pass membrane protein By similarity.
Sequence similarities	Belongs to the dullard family. Contains 1 FCP1 homology domain.
