| Target Information | |
|---|---|
| Target Name | 4EBP |
| Gene Abbr. | EIF4EBP1 |
| Gene ID | 1978 |
| Full Name | eukaryotic translation initiation factor 4E binding protein 1 |
| Alias | 4E-BP1, 4EBP1, BP-1, PHAS-I |
| Introduction | Translation repressor protein 4E-BP1 (also known as PHAS-1) inhibits cap-dependent translation by binding to the translation initiation factor eIF4E. Hyperphosphorylation of 4E-BP1 disrupts this interaction and results in activation of cap-dependent translation. Both the PI3 kinase/Akt pathway and FRAP/mTOR kinase regulate 4E-BP1 activity. Multiple 4E-BP1 residues are phosphorylated in vivo. While phosphorylation by FRAP/mTOR at Thr37 and Thr46 does not prevent the binding of 4E-BP1 to eIF4E, it is thought to prime 4E-BP1 for subsequent phosphorylation at Ser65 and Thr70. |
