This study uses single-molecule fluorescence microscopy to show that ATP binding enables eIF4F redistribution on mRNA, while ATP hydrolysis is required for eIF4F recycling during PIC loading.

The paper identifies a specific 5'-UTR motif, AMAYAA, that eIF3 binds to, enhancing translation under stress conditions.

This study reconstitutes a biochemically active yeast eIF3 complex and shows that eIF3a provides core RNA-binding activity, modulated by interactions with other subunits.
