Abstract

Using an engineered mitochondrial clogger, Krakowczyk et al. (https://doi.org/10.1083/jcb.202306051) identified the OMA1 protease as a critical component that eliminates import failure at the TOM translocase in mammalian cells, providing a novel quality control mechanism that is distinct from those described in yeast.

OMA1 清除了哺乳动物 TOM 隧道中的交通堵塞。
Krakowczyk 等人(https://doi.org/10.1083/jcb.202306051)利用改造的线粒体堵塞器,发现 OMA1 蛋白酶是哺乳动物细胞中消除 TOM 易位酶导入失败的关键部件,提供了一种有别于酵母的新型质量控制机制。
