Comment Type Description
Catalytic Activity Acyl-CoA + 1-acyl-sn-glycero-3- phosphatidylserine = CoA + 1,2-diacyl-sn-glycero-3- phosphatidylserine.
Catalytic Activity Acyl-CoA + 1-acyl-sn-glycero-3-phosphocholine = CoA + 1,2-diacyl-sn-glycero-3-phosphocholine.
Catalytic Activity Acyl-CoA + 1-acyl-sn-glycero-3- phosphoethanolamine = CoA + 1,2-diacyl-sn-glycero-3- phosphoethanolamine.
Disruption Phenotype No visible phenotype under normal growth conditions, but the double mutants lpcat1 and lpcat2-2 show increased contents of very-long-chain fatty acids and decreased polyunsaturated fatty acids in seed triacylglycerols. {ECO:0000269|PubMed:22233193, ECO:0000269|PubMed:22932756, ECO:0000269|PubMed:23150634}.
Function Lysophospholipid acyltransferase with broad specificity. 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 the acylation of lysophosphatidylserine (1-acyl-2-hydroxy-sn-glycero- 3-phospho-L-serine or LPS) into phosphatidylserine (1,2-diacyl-sn- glycero-3-phospho-L-serine or PS) (LPSAT activity). Can convert lysophosphatidylcholine (1-acyl-sn-glycero-3-phosphocholine or LPC) into phosphatidylcholine (1,2-diacyl-sn-glycero-3- phosphocholine or PC) (LPCAT activity) Can also utilizes lysophosphatidylglycerol (LPG) as substrate in vitro. Has neither activity towards lysophosphatidic acid (LPA) nor lysophosphatidylinositol (LPI). Lysophospholipid acyltransferases (LPLATs) catalyze the reacylation step of the phospholipid remodeling pathway also known as the Lands cycle. The primary function of the Lands cycle is to provide a route for acyl remodeling to modify fatty acid (FA) composition of phospholipids derived from the Kennedy pathway. Is involved in PC acyl editing and phosphocholine headgroup exchange between PC and diacylglycerols. This processes control the majority of acyl fluxes through PC to provide polyunsaturated fatty acids for triacylglycerols synthesis in seeds. {ECO:0000269|PubMed:18154737, ECO:0000269|PubMed:22932756, ECO:0000269|PubMed:23150634}.
Sequence Caution Sequence=AAF88094.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305};
Similarity Belongs to the membrane-bound acyltransferase family. {ECO:0000305}.
Subcellular Location Endoplasmic reticulum membrane {ECO:0000305|PubMed:22923678}; Multi-pass membrane protein {ECO:0000305|PubMed:22923678}.
Tissue Specificity Expressed in roots, rosette leaves, petals, stigma, chalazal endosperm of developing seeds and vascular bundles of siliques. {ECO:0000269|PubMed:23150634}.
