Apolipoprotein A-V is a protein that in humans is encoded by the ''APOA5'' gene.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=116519 )〕 The protein encoded by this gene is an apolipoprotein and an important determinant of plasma triglyceride levels, a major risk factor for coronary artery disease. It is a component of several lipoprotein fractions including VLDL, HDL, chylomicrons. It is believed that apoA-V affects lipoprotein metabolism by interacting with LDL-R gene family receptors. This gene uses alternate polyadenylation sites and is located proximal to the apolipoprotein gene cluster on chromosome 11q23.〔 == Discovery == The gene for apolipoprotein A5 (APOA5, gene ID 116519, OMIM accession number – 606368) was originally found by comparative sequencing of human and mice DNA as a last member of the gene cluster of apolipoproteins APOA1/APOC3/APOA4/APOA5, located on human chromosome 11 at position 11q23.〔 The creation of two mice models (APOA5 transgenic and APOA5 knock-out) confirmed the important role of this gene in plasma triglyceride determination. The transgenic mice had lower and the knock-out mice higher levels of plasma triglycerides, while plasma cholesterol levels remained unchanged in both animal models. Interestingly, a Dutch group simultaneously described an identical gene as apolipoprotein which it is associated with the early phase of liver regeneration, but failed to recognise its important role in the determination of plasma triglyceride levels.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「APOA5」の詳細全文を読む スポンサード リンク
