Rapamycin inhibits mTORC1, but not completely

Autophagy. 2009 Jul;5(5):725-6. doi: 10.4161/auto.5.5.8504. Epub 2009 Jul 22.

Abstract

Rapamycin is widely used as a complete inhibitor of the mTORC1 nutrient-sensitive signaling complex. Using a novel ATP-competitive inhibitor named Torin1, we have found that many mTORC1 functions that regulate cap-dependent translation and autophagy are resistant to inhibition by rapamycin.
