mTOR is a conserved protein that integrates anabolic stimuli from resistance exercise and nutrients, and its downstream signals promote protein synthesis and anabolic processes.

“Yeah. I mean, mTOR is one of these...you know, it's a highly conserved protein. It's, sort of, an integrative nexus of all kinds of anabolic stimuli, including resistance exercise, or any form of exercise is actually running through mTOR. Leucine goes through mTOR. Its dysregulation is involved in all kinds of processes, including cancer and lots of other things, so has a really essentially important role in integrating all of those anabolic signals.”
