General annotation (Comments)

Function	Acyltransferase which mediates the conversion of lysophosphatidylethanolamine (1-acyl-sn-glycero-3-phosphoethanolamine or LPE) into phosphatidylethanolamine (1,2-diacyl-sn-glycero-3-phosphoethanolamine or PE) (LPEAT activity). Catalyzes also the acylation of lysophosphatidic acid (LPA) into phosphatidic acid (PA) (LPAAT activity). Has also a very weak lysophosphatidylcholine acyltransferase (LPCAT activity). Prefers oleoyl-CoA as the acyl donor. Lysophospholipid acyltransferases (LPLATs) catalyze the reacylation step of the phospholipid remodeling pathway also known as the Lands cycle. Ref.6
Catalytic activity	Acyl-CoA + 1-acyl-sn-glycero-3-phosphoethanolamine = CoA + 1,2-diacyl-sn-glycero-3-phosphoethanolamine. Acyl-CoA + 1-acyl-sn-glycerol 3-phosphate = CoA + 1,2-diacyl-sn-glycerol 3-phosphate.
Enzyme regulation	Partially inhibited by thimerosal.
Pathway	Lipid metabolism; phospholipid metabolism.
Subcellular location	Membrane; Multi-pass membrane protein Potential.
Tissue specificity	Expressed in neutrophils. Ref.6
Sequence similarities	Belongs to the membrane-bound acyltransferase family.
Sequence caution	The sequence BAC11204.1 differs from that shown. Reason: Erroneous initiation.
