The sufficiency of an amino acid in cells ensures its binding to cognate sensors and suppression of inhibitors of MTOR, leading to increased global protein synthesis. On the other hand, deprivation of amino acids activates the amino acid response pathway (GC

These amino acid sensors control the translocation of mTORC1 from the cytosol to the lysosomal surface where mTORC1 is activated by Rheb GTPase, therefore regulating autophagy and the lysosomal protein degradati
