1 We provide evidence that eIF4E phosphorylation is regulated by mTORC1 by virtue of its interaction with Raptor through a novel TPTPNPP motif and consequent phosphorylation invitro and in vivo in a Rapamycin-sensitive manner. Sirolimus eukaryotic translation initiation factor 4E Homo sapiens
2 While we show that phosphorylation pattern of eIF4E responds faithfully to Rapamycin inhibition, the prolonged exposure to Rapamycin rescues the loss of eIF4E phosphorylation through Mnk1 activation. Sirolimus eukaryotic translation initiation factor 4E Homo sapiens
3 While we show that phosphorylation pattern of eIF4E responds faithfully to Rapamycin inhibition, the prolonged exposure to Rapamycin rescues the loss of eIF4E phosphorylation through Mnk1 activation. Sirolimus eukaryotic translation initiation factor 4E Homo sapiens
4 We also present evidence that eIF4E interacts with the amino terminal domain of S6K1 in a phospho-dependent manner, and this interaction is instrumental in overriding Rapamycin inhibition of S6K1. Sirolimus eukaryotic translation initiation factor 4E Homo sapiens
