Functioni

Provides CDP-diacylglycerol, an important precursor for the synthesis of phosphatidylinositol (PtdIns), phosphatidylglycerol, and cardiolipin. Overexpression may amplify cellular signaling responses from cytokines. May also play an important role in the signal transduction mechanism of retina and neural cells.

Catalytic activityi

CTP + phosphatidate = diphosphate + CDP-diacylglycerol.

Cofactori

Pathwayi: CDP-diacylglycerol biosynthesis

This protein is involved in step 3 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 (cdsA), Phosphatidate cytidylyltransferase, Phosphatidate cytidylyltransferase, Phosphatidate cytidylyltransferase
This subpathway is part of the pathway CDP-diacylglycerol biosynthesis, which is itself part of Phospholipid metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes CDP-diacylglycerol from sn-glycerol 3-phosphate, the pathway CDP-diacylglycerol biosynthesis and in Phospholipid metabolism.
