The mammalian target of rapamycin (mTOR) is a well-conserved negative regulator of autophagy. Here we review our recent data describing how lysosomal positioning influences and coordinates mTOR activity, autophagosome biogenesis and autophagosome-lysosome fusion. In this way, lysosomal positioning regulates many diverse cellular responses to starvation and subsequent nutrient replenishment.
