GPAT3

Glycerol-3-phosphate acyltransferase 3 (GPAT-3) is an enzyme that in humans is encoded by the GPAT3 gene (previously AGPAT9). GPAT-3 has also been called 1-acylglycerol-3-phosphate O-acyltransferase 9 (AGPAT9), lysophosphatidic acid acyltransferase theta (LPAAT-theta), and lung cancer metastasis-associated protein 1.

Function

Glycerol-3-phosphate (G3P) acyltransferases (GPAT; EC 2.3.1.15), such as GPAM and GPAT3 (this enzyme), catalyze the initial step of de novo triacylglycerol (TAG) synthesis by converting glycerol-3-phosphate (G3P) to lysophosphatidic acid (LPA).
