| LIG_eIF4E_1 | 4EBP1_HUMAN | 54 | 60 | Binary | Physicochemical compatibility | Phosphorylation of S65 flanking the eIF4E-binding motif of Eukaryotic translation initiation factor 4E-binding protein 1 (EIF4EBP1) by Serine/threonine-protein kinase mTOR (MTOR) inhibits binding to Eukaryotic translation initiation factor 4E (EIF4E) in response to growth factors and nutrients. This results in release of Eukaryotic translation initiation factor 4E (EIF4E), which associates with other initiation factors to form the eIF-4F complex that mediates initiation of translation. However, disruption of the interaction between Eukaryotic translation initiation factor 4E-binding protein 1 (EIF4EBP1) and Eukaryotic translation initiation factor 4E (EIF4E) has been shown to be dependent on hyperphosphorylation of Eukaryotic translation initiation factor 4E-binding protein 1 (EIF4EBP1) by FRAP/mTOR, PI3K and ERK pathways. According to the current model, Eukaryotic translation initiation factor 4E-binding protein 1 (EIF4EBP1) is phosphorylated on multiple residues in a well-defined order. Basal phosphorylation of T37 and T46 serves as a priming event for subsequent serum-induced phosphorylation of T70, which primes for subsequent phosphorylation of S65. | Curated | |
