Eukaryotic translation initiation factor 4B is a protein that in humans is encoded by the EIF4B gene.[5]
Interactions
eIF4B has been shown to interact with and stimulate the activity of eIF4A and bind to the eIF3 complex through the eIF3A subunit.[6] This interaction results in the recruitment of the eukaryotic small ribosomal subunit (40S) to the mRNA which will in turn set the stage for the later steps leading to elongation.
