Apolipoprotein AI (Apo AI, ApoA-I, Apolipoprotein A1, APOA1) (PE)

Apolipoprotein AI promotes cholesterol efflux from tissues to the liver for excretion. Apolipoprotein AI is the major protein component of high density lipoprotein (HDL) in the plasma. Synthesized in the liver and small intestine, it consists of two identical chains of 77aa; an 18aa signal peptide is removed co-translationally and a 6aa propeptide is cleaved post-translationally. Apolipoprotein A I is a cofactor for lecithin cholesterolacyltransferase (LCAT) which is responsible for the formation of most plasma cholesteryl esters. Defects in the Apolipoprotein A I gene are associated with HDL...
