WebFor example, AMPK inhibits mTORC1 during energetic stress through at least two mechanisms involving AMPK-mediated phosphorylation of Tsc2 on an activating site and raptor on inhibitory sites (23, 24). The regulation and function of mTORC2 remains less well defined than mTORC1. WebNational Center for Biotechnology Information
