Overview of APOB molecular target information


  • Molecular name: APOB, apolipoprotein B
  • Gene family: Apolipoproteins
  • Alias: apolipoprotein B (including Ag(x) antigen)

  • Overview of APOB molecular targets


    Apo B is the major apolipoprotein in chylomicrons, very low density lipoprotein (VLDL), intermediate density lipoprotein (IDL), and low density lipoprotein (LDL) particles, responsible for transporting fat molecules (lipids). Apo B can be divided into two subclasses, Apo B48 and Apo B100, due to differences in amino acid composition. High levels of Apo B, especially together with high concentrations of LDL, are the main driving force for vascular disease (atherosclerosis). Excess Apo B in the liver causes lipid-induced endoplasmic reticulum stress and insulin resistance. Studies have shown that the Apo B-100/Apo A1 ratio is more effective in predicting the risk of heart attack in patients with acute myocardial infarction than measuring Apo B-100 or Apo A1 alone.
