lysophospholipid acyltransferase (LPLAT) family protein may act as an acyltransferase of a de novo or remodeling pathway of glycerophospholipid biosynthesis, catalyzing the incorporation of an acyl group from either acyl-CoAs or acyl-acyl carrier proteins (acyl-ACPs) into acceptors such as glycerol 3-phosphate, dihydroxyacetone phosphate or lyso-phosphatidic acid; 1-acyl-sn-glycerol-3-phosphate acyltransferase, for example, converts lysophosphatidic acid (LPA) into phosphatidic acid by incorporating an acyl moiety at the 2 position by utilizing either acyl-CoA or acyl-ACP as the fatty acyl donor;

This model describes the core homologous region of a collection of related proteins, several of which are known to act as 1-acyl-sn-glycerol-3-phosphate acyltransferases (EC 2.3.1.51). Proteins scoring above the trusted cutoff are likely to have the same general activity. However, there is variation among characterized members as to whether the acyl group can be donated by acyl carrier protein or coenzyme A, and in the length and saturation of the donated acyl group. 1-acyl-sn-glycerol-3-phosphate acyltransferase is also called 1-AGP acyltransferase, lysophosphatidic acid acyltransferase, and LPA acyltransferase.
