Scientific Background: 4E-BP1 (PHAS-1) acts downstream of the MAP kinase and TORC1 signalling pathways to inhibit EIF4E activity to promote translation initiation by preventing its assembly into the eIF4F complex. The hypophosphorylated form of 4E-BP1 competes with EIF4G1/EIF4G3 and strongly binds to EIF4E to repress translation. The hyperphosphorylated form of 4E-BP1 dissociates from EIF4E, and permits interaction between EIF4G1/EIF4G3 and EIF4E, leading to initiation of translation.
