Apolipoprotein A1 (ApoA1) is a 28 kDa glycoprotein and the primary protein component of high-density lipoprotein (HDL) particles. HDL particles are central to the reverse cholesterol transport process, moving cholesterol from peripheral tissues to the liver for excretion. ApoA1 plays a specific role in lipid metabolism. Chylomicrons, secreted from intestinal enterocytes, contain ApoA1, which is rapidly transferred to HDL in the bloodstream. This protein facilitates cholesterol efflux from tissues to the liver and serves as a cofactor for lecithin cholesterol acyltransferase (LCAT), an enzyme responsible for the formation of most plasma cholesteryl esters. ApoA1 binds to the scavenger receptor class B type I (SR-BI) and the beta chain of ATP synthase on hepatocytes. Hepatocytes then internalize these particles and transfer cholesterol into bile for excretion.
