分子伴娘的功能是介导其它蛋白质的正确折叠和装配,但它本身却不是有功能的最终装配产物的组成成分。α晶体蛋白作为晶体中重要的成分蛋白,具有分子伴娘样活性,对各种变性剂包括加热、紫外线照射和化学处理造成的蛋白质非特异性的凝聚具有抑制作用,对糖基化诱导的重要的代谢和抗氧化酶的失活具有保护作用。α晶体蛋白分子伴娘作用的丧失与白内障发病密切相关。本文就其研究现状及前景作扼要综述。 The function of a molecular bridesmaid is to mediate the correct folding and assembly of other proteins, but it is not in itself a component of a functional final assembly product. Alpha crystal protein, as an important component protein in crystal, has the molecular activity of bridesmaid-like activity and inhibits the non-specific aggregation of proteins caused by various denaturants, including heating, UV irradiation and chemical treatment, and plays an important role in glycosylation-induced metabolism And antioxidant enzyme has a protective effect of inactivation. α crystal protein molecules loss of bridesmaids and cataract incidence are closely related. This article gives a brief overview of its research status and prospects.
