Protein attributes

Sequence length	446 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Esterifies acyl-group from acyl-ACP to the sn-1 position of glycerol-3-phosphate, an essential step in glycerolipid biosynthesis By similarity.
Catalytic activity	Acyl-CoA + sn-glycerol 3-phosphate = CoA + 1-acyl-sn-glycerol 3-phosphate.
Pathway	Glycerolipid metabolism; triacylglycerol biosynthesis. Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 1/3.
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.
