载脂蛋白Ｅ（ａｐｏＥ）由２９９个氨基酸残基组成，分子量３４２０ＫＤ，是一种多功能糖蛋白，在脂类运输及调节脂蛋白和脂类代谢过程中起作用。ａｐｏＥ基因位于１９号染色体长臂（１９ｑ１３）上〔１〕，基因位点存在多态性，有３种常见的等位基因ε２、ε３、ε４，...
Apolipoprotein E (apoE) consists of 299 amino acid residues and has a molecular weight of 34.20 KD. It is a multifunctional glycoprotein that plays a role in the transport of lipids and in the regulation of lipoproteins and lipid metabolism. The apoE gene is located on the long arm of chromosome 19 (19q13) [1]. There are polymorphisms in the gene locus. There are three common alleles ε2, ε3, ε4, ...
