细胞质伴侣蛋白在应激条件下稳定细胞蛋白,并在正常生长过程中保护新生蛋白链。Young等人(2003)的最新数据扩展了伴侣蛋白的功能,证明Hsp90和Hsp70在外膜特异性地与线粒体蛋白输入受体Tom70相互作用,并且是前体蛋白易位所必需的。
Cytosolic chaperones stabilize cellular proteins under stress conditions and protect nascent protein chains during normal growth. Recent data from Young et al. (2003) extend the function of chaperones by demonstrating that Hsp90 and Hsp70 specifically interact with the mitochondrial protein import receptor Tom70 at the outer membrane and are required for translocation of precursor proteins.
