Amino acids stimulate glycyl‐tRNA synthetase nuclear localization for mammalian target of rapamycin expression in bovine mammary epithelial cells

Amino acids are required for the activation of mammalian target of rapamycin (mTOR) to increase cell growth, protein and lipid synthesis, and inhibit autophagy. However, the mechanism through which amino acids activate the mTOR signaling is still largely unknown. In our previous study, we discovered that glycyl-tRNA synthetase (GlyRS) is a key mediator of amino-acid-induced mTOR expression and activation in bovine mammary epithelial cells...
