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. Induces neuronal differentiation by antagonizing BMP signaling. Acts both by dephosphorylating BMPR1A and by promoting BMPR2 proteasomal degradation By similarity.

Catalytic activity

[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.

Subunit structure

Interacts with bmpr1a, bmpr1b and bmpr2 By similarity.

Subcellular location

Membrane; Single-pass membrane protein Potential. Cytoplasmperinuclear region By similarity.

Sequence similarities

Belongs to the dullard family.

Contains 1 FCP1 homology domain.
