APOA1 - apolipoprotein A1 Gene
Also Known as HPALP2; apo(a)
Species: Homo sapiens
About APOA1
This gene has 5 transcripts (splice variants), 193 orthologues, 3 paralogues and is associated with 6 phenotypes. Biased expression in liver (RPKM 4032.4), small intestine (RPKM 1199.8) and 1 other tissue.
Summary
This gene encodes Apolipoprotein A-I, which is the major protein component of high density lipoprotein (HDL) in plasma. The encoded preproprotein is proteolytically processed to generate the mature protein, which promotes Cholesterol efflux from tissues to the liver for excretion, and is a cofactor for lecithin cholesterolacyltransferase (LCAT), an enzyme responsible for the formation of most plasma cholesteryl esters. This gene is closely linked with two other Apolipoprotein genes on chromosome 11. Defects in this gene are associated with HDL deficiencies, including Tangier disease, and with systemic non-neuropathic amyloidosis. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein. [provided by RefSeq, Dec 2015]
