Protein attributes

Sequence length	390 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Converts lysophosphatidic acid (LPA) into phosphatidic acid by incorporating acyl moiety at the 2 position 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	Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity.
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.
