Gene

Gpam

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Esterifies acyl-group from acyl-ACP to the sn-1 position of glycerol-3-phosphate, an essential step in glycerolipid biosynthesis.By similarity

Catalytic activityi

Acyl-CoA + sn-glycerol 3-phosphate = CoA + 1-acyl-sn-glycerol 3-phosphate.

Pathwayi: CDP-diacylglycerol biosynthesis

This protein is involved in step 1 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 4 (Gpat4), Glycerol-3-phosphate acyltransferase 3 (Gpat3), Glycerol-3-phosphate acyltransferase 2, mitochondrial (Gpat2)
  2. 1-acyl-sn-glycerol-3-phosphate acyltransferase gamma (Agpat3), 1-acyl-sn-glycerol-3-phosphate acyltransferase beta (Agpat2), 1-acyl-sn-glycerol-3-phosphate acyltransferase alpha (Agpat1), Lysocardiolipin acyltransferase 1 (Lclat1), 1-acyl-sn-glycerol-3-phosphate acyltransferase epsilon (Agpat5), 1-acyl-sn-glycerol-3-phosphate acyltransferase delta (Agpat4)
  3. Phosphatidate cytidylyltransferase, mitochondrial (Tamm41), Phosphatidate cytidylyltransferase, mitochondrial (Tamm41), Phosphatidate cytidylyltransferase (Cds2), Phosphatidate cytidylyltransferase (Cds2), Phosphatidate cytidylyltransferase 2 (Cds2), Phosphatidate cytidylyltransferase (Cds2), Phosphatidate cytidylyltransferase 1 (Cds1)
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.
