Apolipoprotein A II is the second most abundant protein of the high density lipoprotein particles, accounting for 20% of protein mass of HDL. The concentration of ApoA-I and ApoA-II is inversely correlated with the frequency of heart disease in human (1). In studies with mice and humans, ApoA-II levels have been associated with increased susceptibility to atherosclerosis, increased free fatty acid levels, increased body fat, and increased insulin resistance (2). ApoA-II consists of three potential amphipathic helices of 17 residues each, which contribute to the lipid-binding properties of this apolipoprotein (3). Currently, the best characterized activity of apoA-II is its potent antagonism of the anti-atherogenic and anti-inflammatory activities of ApoA-I, probably due to its competition with the latter for lipid acyl side chains of HDL (1).
