Glycerol-3-phosphate acyltransferase 4 is a protein that in humans is encoded by the GPAT4 gene. [5]

Contents

Function

GPAT4 is involved in the biosynthesis of triglycerides. [6] The majority of triglycerides are synthesised from glycerol 3-phosphate (G3P) via the addition of three fatty acyl-CoA substrates, which are made from fatty acids. The first of these additions is catalysed by G3P acyltransferases (GPATs: EC 2.3.1.15), including GPAT4, yielding lysophosphatidic acid. [7] GPAT4 has been shown to be important for lactation, with QTL for several milk production and composition traits observed at this locus in cattle. [8]

Lipolysis Metabolism involving breakdown of lipids

Lipolysis is the metabolic pathway through which lipid triglycerides are hydrolyzed into a glycerol and three fatty acids. It is used to mobilize stored energy during fasting or exercise, and usually occurs in fat adipocytes. The most important regulatory hormone in lipolysis is insulin; lipolysis can only occur when insulin action falls to low levels, as occurs during fasting. Other hormones that affect lipolysis include glucagon, epinephrine, norepinephrine, growth hormone, atrial natriuretic peptide, brain natriuretic peptide, and cortisol.

Adipose triglyceride lipase, also known as patatin-like phospholipase domain-containing protein 2 and ATGL, is an enzyme that in humans is encoded by the PNPLA2 gene. ATGL catalyses the first reaction of lipolysis, where triacylglycerols are hydrolysed to diacylglycerols.

AGPAT3

1-acyl-sn-glycerol-3-phosphate acyltransferase gamma is an enzyme that in humans is encoded by the AGPAT3 gene. The protein encoded by this gene is an acyltransferase that converts lysophosphatidic acid into phosphatidic acid, which is the second step in the de novo phospholipid biosynthetic pathway. The encoded protein may be an integral membrane protein. Two transcript variants encoding the same protein have been found for this gene.
