Protein attributes

Sequence length	276 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the conversion of phosphatidic acid (PA) to diacylglycerol (DG). In addition it hydrolyzes lysophosphatidic acid (LPA), ceramide-1-phosphate (C-1-P) and sphingosine-1-phosphate (S-1-P) By similarity.
Catalytic activity	A 3-sn-phosphatidate + H2O = a 1,2-diacyl-sn-glycerol + phosphate.
Subunit structure	Homodimer By similarity.
Subcellular location	Membrane; Multi-pass membrane protein.
Tissue specificity	Expressed at high levels in lung, liver and kidney; at low levels in heart and brain, and was not detected in skeletal muscle.
Sequence similarities	Belongs to the PA-phosphatase related phosphoesterase family.
