Overview of APOA2 molecular target information


  • Molecular name: APOA2, apolipoprotein A2
  • Gene family: Apolipoproteins
  • Alias: apolipoprotein A-II

  • Overview of APOA2 molecular targets


    Apolipoprotein AII (Apo A2) is the second most abundant apolipoprotein in human plasma high-density lipoprotein (HDL) after Apo A1 and is the most hydrophilic of the exchangeable apolipoproteins. Apo A2 is synthesized by the liver and small intestine and exists in plasma as a monomer or dimer. The Apo A2 gene consists of 4 exons and 3 introns. The four exons encode the 5' untranslated region, the propeptide, a short N-terminal domain, and a C-terminal domain consisting of a variable number of lipid-binding amphipathic helices. Apo A2 can stabilize the HDL structure by binding lipids and affect HDL metabolism. The role of Apo A2 in lipid metabolism and atherosclerosis has shown important clinical significance. Apo A2 levels are associated with increased susceptibility to atherosclerosis, free fatty acid levels, body fat, and insulin resistance.
