Molecular mechanisms through which amino acids mediate signaling through the mammalian target of rapamycin

Studies reported in the past 18 months have greatly expanded our knowledge of one of the signaling pathways through which amino acids act to regulate mTOR and also the molecular interactions that mediate the interaction between mTOR and two downstream substrates, eukaryotic initiation factor 4E binding protein 1 and ribosomal protein S6 kinase.
