| 摘 要： | 硒蛋白S是一种新发现的内质网和细胞膜驻留硒蛋白。以往的研究结果揭示硒蛋白S可以保护细胞拮抗氧化损伤及内质网应激诱导的细胞凋亡;参与脂蛋白代谢、精子发育过程、炎症反应及将错误折叠蛋白从内质网腔逆向转移到细胞质中然后降解的过程(即内质网相关蛋白降解)。硒蛋白S基因多态性与糖尿病、冠状动脉心脏病或先兆子痫等疾病密切相关。本文结合本课题组的工作对硒蛋白S的最新研究进展,尤其是硒蛋白S功能的研究成果作了较为详细的介绍,并对未来的研究方向作了展望。

| Abstract: | Selenoprotein S(SelS) is a new endoplasmic reticulum(ER) and plasma membrane resident selenoprotein.Previous studies reveal that SelS protects cells from oxidative damage and endoplasmic reticulum stress-induced apoptosis.It participates in the retro-translocation of misfolded proteins from the ER lumen to cytosol for degradation(ER-associated protein degradation).SelS is involved in spermatogenesis,lipoprotein metabolism and the regulation of inflammatory response.Polymorphism of SelS is closely associated... |
