Figure 1 Amino Acid-Induced mTORC1 Activation
In amino acid-deprived cells, the lysosome-associated Ragulator-Rag complex contains RagBGDP and mTORC1 is diffusely distributed through the cytoplasm in an inactive state. Amino acids stimulate the formation of RagBGTPRagDGDP heterodimers, and, in turn, the association of the Raptor subunit of mTORC1 with the Rag-Ragulator complex. The resulting supercomplex promotes the interaction of mTORC1 with active RhebGTP, which stimulates mTORC1 kinase activity, and drives the phosphorylation of downstream effectors such as S6K1.
