Converts lysophosphatidic acid (LPA) into phosphatidic acid by incorporating an acyl moiety at the sn-2 position of the glycerol backbone.
Expressed predominantly in heart and liver.
Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 2/3.
Involvement in disease
Defects in AGPAT2 are the cause of congenital generalized lipodystrophy type 1 (CGL1) [MIM:608594]; also known as Berardinelli-Seip congenital lipodystrophy type 1 (BSCL1) or Berardinelli-Seip syndrome. CGL1 is an autosomal recessive disorder characterized by marked paucity of adipose tissue, extreme insulin resistance, hypertriglyceridemia, hepatic steatosis and early onset of diabetes.
Belongs to the 1-acyl-sn-glycerol-3-phosphate acyltransferase family.
The HXXXXD motif is essential for acyltransferase activity and may constitute the binding site for the phosphate moiety of the glycerol-3-phosphate.
