Acyl-CoA: glycerol-3-phosphate acyltransferase (GPAT) catalyzes the first step during de
novo synthesis of glycerolipids. Mammals have at least four GPAT isoforms. Here we report
the further characterization of the two recently identified microsomal GPAT3 and GPAT4.
Both enzymes are highly expressed in adipose tissues. However, while GPAT3 is highly (∼
60-fold) induced during adipocyte differentiation, GPAT4 induction is only modest (∼ 5-fold),
leading to a lower abundance of GPAT4 mRNA in adipocytes. While overexpression of …
