mTOR and lysosome regulation

Lysosomes are key cellular organelles that play a crucial role in catabolism by degrading extracellular and intracellular material. It is, therefore, very intriguing that mTORC1 (mechanistic target of rapamycin complex 1), a major promoter of anabolic processes, localizes in its active form to the surface of lysosomes. In recent years, many exciting observations have revealed a tightly regulated crosstalk between mTORC1 activity and lysosomal function. These findings highlight the complex regulatory network that modulates energy metabolism in cells.
