Apolipoprotein A-II is a protein that in humans is encoded by the APOA2 gene.^[5] It is the second most abundant protein of the high density lipoprotein particles. The protein is found in plasma as a monomer, homodimer, or heterodimer with apolipoprotein D. ApoA-II regulates many steps in HDL metabolism, and its role in coronary heart disease is unclear. ^[6] Remarkably, defects in this gene may result in apolipoprotein A-II deficiency or hypercholesterolemia.^[7]

Interactions

ApoA-II has been shown to interact with phospholipid transfer protein.^[8]
