A component of high density lipoproteins. It is instrumental in promoting efflux of cholesterol from extrahepatic tissue to the liver where it is metabolized and excreted from the body. This protein modulates the activation of lecithin-cholesterol acyltransferase in the presence of apolipoprotein A-I. Source: National Library of Medicine, MeSH 2006

Apolipoproteins are a family of proteins involved in cholesterol transport and metabolism. Apoliprotein A is an important component of high-density lipoprotein (HDL or "good" cholesterol) and has several subtypes, including A-I and A-II, which are encoded by the APOA1 and APOA2 genes, respectively. A-I and A-II are the primary protein components of HDL. Deficiency of apolipoprotein A-I is associated with low HDL levels [], while deficiency of A-II is not associated with significant changes in HDL or other lipid levels [UniProt: P02652].
