UniProtKB - Q9HDD0 (PLAT1_HUMAN)
Protein
Phospholipase A and acyltransferase 1
Gene
PLAAT1
Organism
Homo sapiens (Human)
Status
Functioni
Exhibits both phospholipase A1/2 and acyltransferase activities (PubMed:21880860, PubMed:26503625). Shows phospholipase A1 (PLA1) and A2 (PLA2) activity, catalyzing the calcium-independent release of fatty acids from the sn-1 or sn-2 position of glycerophospholipids (PubMed:21880860, PubMed:22825852, PubMed:27623847). Shows O-acyltransferase activity, catalyzing the transfer of a fatty acyl group from glycerophospholipid to the hydroxyl group of lysophospholipid (PubMed:21880860). Shows N-acyltransferase activity, catalyzing the calcium-independent transfer of a fatty acyl group at the sn-1 position of phosphatidylcholine (PC) and other glycerophospholipids to the primary amine of phosphatidylethanolamine (PE), forming N-acylphosphatidylethanolamine (NAPE) which serves as precursor for N-acylethanolamines (NAEs) (PubMed:21880860, PubMed:22825852, PubMed:27623847).1 Publication3 Publications
