Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Converts lysophosphatidic acid (LPA) into phosphatidic acid by incorporating an acyl moiety at the sn-2 position of the glycerol backbone.1 Publication

Catalytic activityi

Acyl-CoA + 1-acyl-sn-glycerol 3-phosphate = CoA + 1,2-diacyl-sn-glycerol 3-phosphate.1 Publication

Pathwayi: CDP-diacylglycerol biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes CDP-diacylglycerol from sn-glycerol 3-phosphate.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Glycerol-3-phosphate acyltransferase 2, mitochondrial (GPAT2), Glycerol-3-phosphate acyltransferase 1, mitochondrial (GPAM), Glycerol-3-phosphate acyltransferase 1, mitochondrial (GPAM), Glycerol-3-phosphate acyltransferase 4 (GPAT4), Glycerol-3-phosphate acyltransferase 3 (GPAT3), Glycerol-3-phosphate acyltransferase 1, mitochondrial, Glycerol-3-phosphate acyltransferase 1, mitochondrial (GPAM), Glycerol-3-phosphate acyltransferase 1, mitochondrial (DKFZp451B1115)
  2. 1-acyl-sn-glycerol-3-phosphate acyltransferase beta (AGPAT2), 1-acyl-sn-glycerol-3-phosphate acyltransferase delta (AGPAT4), 1-acyl-sn-glycerol-3-phosphate acyltransferase gamma (AGPAT3), 1-acyl-sn-glycerol-3-phosphate acyltransferase epsilon (AGPAT5), 1-acyl-sn-glycerol-3-phosphate acyltransferase alpha (AGPAT1), Lysocardiolipin acyltransferase 1 (LCLAT1)
  3. Phosphatidate cytidylyltransferase 1 (CDS1), Phosphatidate cytidylyltransferase 2 (CDS2), Phosphatidate cytidylyltransferase, mitochondrial (TAMM41), Phosphatidate cytidylyltransferase (CDS1), Phosphatidate cytidylyltransferase, Phosphatidate cytidylyltransferase, Phosphatidate cytidylyltransferase, Phosphatidate cytidylyltransferase
This subpathway is part of the pathway CDP-diacylglycerol biosynthesis, which is itself part of Phospholipid metabolism.
