Abstract
By analysis of a temperature-sensitive yeast mutant, a heat-shock protein in the matrix of mitochondria, mitochondrial hsp70 (Ssc1p), is found to be involved both in translocation of nuclear-encoded precursor proteins across the mitochondrial membranes and in (re)folding of imported proteins in the matrix.
摘要
通过对一种温度敏感型酵母突变体的分析，发现线粒体基质中的一种热休克蛋白——线粒体hsp70（Ssc1p），既参与核编码前体蛋白穿过线粒体膜的转运过程，又参与基质中输入蛋白的（再）折叠过程。
