Dissecting the biology of mTORC1 beyond rapamycin

Rapamycin extends maximal life span and increases resistance to starvation in many organisms. The beneficial effects of rapamycin are thought to be mediated by its inhibitory effects on the mechanistic target of rapamycin complex 1 (mTORC1), although it only partially inhibits the kinase activity of mTORC1. Other mTOR kinase inhibitors have been developed, such as Torin-1, but these readily cross-react with mTORC2. Here, we report the distinct...
