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 1, mitochondrial (GPAM), Glycerol-3-phosphate acyltransferase 1, mitochondrial (GPAM), Glycerol-3-phosphate acyltransferase 1, mitochondrial (GPAM), Glycerol-3-phosphate acyltransferase 4 (GPAT4)
  2. 1-acyl-sn-glycerol-3-phosphate acyltransferase delta (AGPAT4), 1-acyl-sn-glycerol-3-phosphate acyltransferase alpha (AGPAT1)
  3. Phosphatidate cytidylyltransferase, mitochondrial (TAMM41), Phosphatidate cytidylyltransferase, mitochondrial (TAMM41), Phosphatidate cytidylyltransferase 2 (CDS2), CDP-diacylglycerol synthase, Phosphatidate cytidylyltransferase (CDS1), Phosphatidate cytidylyltransferase, mitochondrial (TAMM41)
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.
