1-acyl-sn-glycerol-3-phosphate acyltransferase alpha; 1-acylglycerol-3-phosphate O-acyltransferase 1; 1-AGP acyltransferase 1; 1-AGPAT 1; lysophosphatidic acid acyltransferase alpha; LPAAT-alpha; protein G15 (AGPAT1, G15)

Function

• converts lysophosphatidic acid (LPA) into phosphatidic acid by incorporating an acyl moiety at the sn-2 position of the glycerol backbone
• 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

membrane (potential)

More general terms

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