mTORC1 regulation of protein synthesis. mTOR is a heavily regulated kinase that promotes cell growth and division following cell receipt of nutrients or growth factors. This schematic depicts a growth factor resulting in AKT and PDK1 activation by PI3K. AKT inhibits TSC1/2, enabling mTOR activation. mTOR regulates protein synthesis through S6K and 4E-BPs.
