Previous GeneCards Identifiers for APOA1 Gene
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]
GeneCards Summary for APOA1 Gene
APOA1 (Apolipoprotein A1) is a Protein Coding gene. Diseases associated with APOA1 include Hypoalphalipoproteinemia, Primary, 2 and Amyloidosis, Familial Visceral. Among its related pathways are Lipoprotein metabolism and Folate Metabolism. Gene Ontology (GO) annotations related to this gene include identical protein binding and lipid binding. An important paralog of this gene is APOA4.
UniProtKB/Swiss-Prot Summary for APOA1 Gene
Participates in the reverse transport of cholesterol from tissues to the liver for excretion by promoting cholesterol efflux from tissues and by acting as a cofactor for the lecithin cholesterol acyltransferase (LCAT). As part of the SPAP complex, activates spermatozoa motility.
