چکیده انگلیسی
mTORC1, a kinase complex that is considered a master regulator of cellular growth and proliferation, is regulated by many extra- and intracellular signals. Among these signals, mitochondrial status is known to have an impact on the effects of mTORC1 on cell growth and survival. However, how mitochondrial status affects mTORC1 activity, notably the molecular link, is not fully elucidated. Here, we found that Parkin can interact with and ubiquitinate mTOR. We also identified K2066 and K2306 as Parkin-dependent and mitochondrial stress-induced mTOR ubiquitination residues. This ubiquitination by Parkin is required for maintenance of mTORC1 activity under mitochondrial stress. With regard to the physiological meaning of mTORC1 activity under mitochondrial stress, we suggest that mTORC1 plays a pro-survival role.
