1-acyl-sn-glycerol-3-phosphate acyltransferase gamma; 1-acylglycerol-3-phosphate O-acyltransferase 3; 1-AGP acyltransferase 3; 1-AGPAT 3; lysophosphatidic acid acyltransferase gamma; LPAAT-gamma (AGPAT3)

Function

• converts lysophosphatidic acid (LPA) into phosphatidic acid by incorporating an acyl moiety at the sn-2 position of the glycerol backbone (putative)
• phospholipid metabolism; CDP-diacylglycerol biosynthesis
• CDP-diacylglycerol from sn-glycerol 3-phosphate: step 2/3

acyl-CoA + 1-acyl-sn-glycerol 3-phosphate =

CoA + 1,2-diacyl-sn-glycerol 3-phosphate

Structure

• the HXXXXD motif is essential for acyltransferase activity & may constitute the binding site for the phosphate moiety of the glycerol-3-phosphate (putative)
• belongs to the 1-acyl-sn-glycerol-3-phosphate acyltransferase family

Compartment

• endoplasmic reticulum membrane

Alternative splicing

named isoforms=3

More general terms

• 1-acyl-sn-glycerol-3-phosphate acyltransferase
• transmembrane 2 protein
