Lp-PLA2 is an alias for the gene, Phospholipase A2 group VII, in humans. Other names include: 1-alkyl-2-acetylglycerophosphocholine esterase; 2-acetyl-1-alkylglycerophosphocholine esterase; Group-VIIA phospholipase A2; gVIIA-PLA2; LDL-associated phospholipase A2; LDL-PLA(2); PAF 2-acylhydrolase; PAF acetylhydrolase; LDL-PLA2; LP-PLA2; PAFAD; phospholipase A2, group VII (platelet-activating factor acetylhydrolase, plasma). The encoded protein is an enzyme with an amino acid length of 441 and a mass of 50.1 kDa. Other isoforms may exist. Lp-PLA2 is a member of the AB hydrolase superfamily, Lipase family. This gene shares homology with other species, including: Mouse, Rat, Zebrafish, Frog, Chicken.
