Translational activation of uncapped mRNAs by the central part of human eIF4G is 5′ end-dependent

Abstract excerpt

Translation initiation factor (eIF) 4G represents a critical link between mRNAs and 40S ribosomal subunits during translation initiation. It interacts directly with the cap-binding protein eIF4E through its N-terminal part, and binds eIF3 and eIF4A through the central and C-terminal region. We expressed and purified recombinant variants of human eIF4G lacking the N-terminal domain as GST-fusion proteins, and...
