Abstract excerpt
Employing specific inhibitors and docking-site mutants of growth factor receptors, recent studies have indicated that the insulin-induced increase in 40S ribosomal protein S6 and initiation factor 4E binding protein 1 (4E-BP1) phosphorylation is mediated by the mTOR/FRAP-p70s6k signal transduction pathway. However, it has not been resolved whether the phosphorylation of both proteins is mediated by p70s6k or...
