Interactioni

Subunit structurei

eIF4F is a multi-subunit complex, the composition of which varies with external and internal environmental conditions. It is composed of at least eIF4A, eIF4E and eIF4G. eIF4E is also known to interact with other partners (By similarity). EIF4E2 interacts with EIF4EBP1, EIF4EBP2 and EIF4EBP3 but not with eIF4G.By similarity2 Publications
