热休克蛋白是一组较为保守的蛋白,是细胞抵御恶劣环境的主要蛋白之一.近来对其结构及功能的研究有了长足的进步,发现了许多新的功能如热休克蛋白在分子伴侣、肿瘤抗原的提呈及肿瘤细胞的抗凋亡等.本文就热休克蛋白70的结构及其生物学功能上的新进展作一概述, Heat shock proteins are a group of relatively conserved proteins, and they are one of the major proteins in cells to withstand harsh environments. Recently, there have been significant advances in the study of their structure and function, and many new functions such as heat shock proteins have been discovered in molecular chaperones. The presentation of tumor antigens and the anti-apoptosis of tumor cells. This article gives an overview of the structure and biological function of heat shock protein 70.
