WebDec 14, 2024 · The mechanistic target of rapamycin complex1 (mTORC1) controls cell growth, proliferation and metabolism in response to diverse stimuli. This study identifies a new auto-regulatory branch of mTORC1 signaling involving phosphorylation of the Rag GTPase RagC by mTORC1, which is required for full mTORC1 activation by growth factors … Almost all of the variables required for protein synthesis affect mTORC1 activation by interacting with the TSC1/TSC2 protein complex. TSC2 is a GTPase activating protein (GAP). Its GAP activity interacts with a G protein called Rheb by hydrolyzing the GTP of the active Rheb-GTP complex, converting it to the inactive Rheb-GDP complex. The active Rheb-GTP activates mTORC1 through unelucid…

WebActive Rag recruits mTORC1 to Rheb on the surface of the lysosome. Rag was originally suggested to deliver mTORC1 from the cytoplasm to the lysosome, with the implication that Rag itself shuttles on and off the lysosome ( Sancak et al., 2008; Zinzalla and Hall, 2008 ). WebAug 10, 2012 · Rag-dependent recruitment of mTORC1 to the lysosome is an essential step in the activation of mTORC1 by amino acids. We next examined if glutaminolysis is required for the recruitment of mTORC1 to the lysosome.
