Protein

1-acyl-sn-glycerol-3-phosphate acyltransferase gamma

Gene

Agpat3

Organism
Mus musculus (Mouse)
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 (PubMed:15367102). Acts on LPA containing saturated or unsaturated fatty acids C16:0-C20:4 at the sn-1 position using C18:1, C20:4 or C18:2-CoA as the acyl donor. Also acts on lysophosphatidylcholine, lysophosphatidylinositol and lysophosphatidylserine using C18:1 or C20:4-CoA (By similarity). Has a preference for arachidonoyl-CoA as a donor (PubMed:19114731). Has also a modest lysophosphatidylinositol acyltransferase (LPIAT) activity, converts lysophosphatidylinositol (LPI) into phosphatidylinositol (PubMed:19114731).By similarity2 Publications

Catalytic activityi

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

Enzyme regulationi

In males, activity increases in an age-dependent fashion, maybe derived from the induction by sex-hormones.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 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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
