 eIF4G stands for eukaryotic initiation factor 4 gamma (typically gamma is now replaced by G in the literature).It was initially isolated by fractionation, found present in fraction 4 gamma, and was involved in eukaryotic translation initiation.eIF4G has been found to associate with many other proteins besides those of the eIF4F complex, including MNK-1, CBP80, CBP20, PABP, and eIF3.
