Protein attributes

Sequence length	364 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Converts lysophosphatidic acid (LPA) into phosphatidic acid by incorporating an acyl moiety at the sn-2 position of the glycerol backbone By similarity.
Catalytic activity	Acyl-CoA + 1-acyl-sn-glycerol 3-phosphate = CoA + 1,2-diacyl-sn-glycerol 3-phosphate.
Pathway	Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 2/3.
Subcellular location	Membrane; Multi-pass membrane proteinPotential.
Domain	The HXXXXD motif is essential for acyltransferase activity and may constitute the binding site for the phosphate moiety of the glycerol-3-phosphate By similarity.
Sequence similarities	Belongs to the 1-acyl-sn-glycerol-3-phosphate acyltransferase family.
Caution	It is uncertain whether Met-1 or Met-12 is the initiator.
