FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Apoliprotein (apo) A-IV gene contains 3 exons separated by two introns. A sequence polymorphism has been identified in the 3'UTR of the third exon. The primary translation product is a 396-residue preprotein which after proteolytic processing is secreted its primary site of synthesis, the intestine, in association with chylomicron particles. Although its precise function is not known, apo A-IV is a potent activator of lecithin-cholesterol acyltransferase in vitro. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for disruption of this gene have lower HDL cholesterol levels but normal lipid absorption, growth, and feeding behavior. [provided by MGI curators]
