Cell metabolism and growth are matched to nutrient availability via the amino-acid-regulated mechanistic target of rapamycin complex 1 (mTORC1). Transporters have emerged as important amino acid sensors controlling mTOR recruitment and activation at the surface of multiple intracellular compartments. Classically, this has involved late endosomes and lysosomes, but now, in a recent twist, also the Golgi apparatus. Here we propose a model in which specific amino acids in assorted compartments activate different mTORC1 complexes, which may have distinct drug sensitivities and functions. We will discuss the implications of this for mTORC1 function in health and disease. Cell metabolism and growth are matched to nutrient availability via amino-acid-regulated mechanistic target of rapamycin complex 1 (mTORC1). Goberdhan et al. review evidence that amino acid transporters on different subcellular compartments act as amino acid sensors in this process and discuss implications for mTORC1 function in health and disease.
