| Type | subunit | Description | Hypophosphorylated EIF4EBP1 competes with EIF4G1/EIF4G3 to interact with EIF4E; insulin stimulated MAP-kinase (MAPK1 and MAPK3) or mTORC1 phosphorylation of EIF4EBP1 causes dissociation of the complex allowing EIF4G1/EIF4G3 to bind and consequent initiation of translation (PubMed:7629182). Interacts (via TOS motif) with RPTOR; promoting phosphorylation by mTORC1 (PubMed:24139800). |
