Lysolipid acyltransferase; involved in the synthesis of phosphatidic acid from 1-acyl-2-hydroxy-sn-glycero-3-phosphate using oleoyl-CoA as acyl donor and in phospholipid remodeling, incorporating palmitic acid into the sn-1 position of phosphatidylserine and phosphatidylethanolamine; localizes to ER membranes associated with mitochondria (MAMs); contains three predicted transmembrane domains; similar to C. elegans F55A11.5 and maize 1-acyl-glycerol-3-phosphate acyltransferase
