The everolimus-FKBP12 complex binds to mTOR and reduces the activity of the downstream effectors S6 ribosomal protein kinase (S6K1) and translational repressor protein eukaryotic elongation factor 4E-binding protein (4EBP).19 eIF-4F activation results in the translation of a subset of capped mRNA containing highly structured 5? | |||||||||||||||
| |||||||||||||||
|
An important feature of the PV genomic RNA, a mRNA, that distinguishes it from most cellular mRNAs, is the absence of a 7-methyl guanosine (m7G) cap structure, which in cellular mRNAs interacts with the eIF4F cap-binding complex early in translation initiation of cellular proteins. | |||||||||||||||
| |||||||||||||||
|
This interaction, which was not included in the model, was at least partially responsible for TOR activation and the eventual liberation of eIF4E. | |||||||||||||||

|
Active hypophosphorylated forms of 4E-BPs bind to eIF4E, compete with eIF4G, and inhibit eIF4G binding to eIF4E, which prevents eIF4F complex formation and inhibits cap-dependent translation (18). | |||||||||||||||
| |||||||||||||||
|
This allows eIF4E to bind eIF4G and formation of the eIF4F complex, which leads to translation activation (18). | |||||||||||||||
| |||||||||||||||
|
We studied the phosphorylation status of 4E-BP1 associated with eIF4E and the binding of eIF4G to eIF4E as eIF4F complex formation. eIF4E is identified by its ability to bind to the 5? | |||||||||||||||
| |||||||||||||||
|
To study eIF4F complex formation and 4E-BP1 and eIF4G association with eIF4E, a cap-containing matrix was used as described previously (16, 19). | |||||||||||||||
