Offers no immediate clinical application; extends molecular insights into cap-dependent translation but remains hypothesis-generating.
The presence of eIF4B and PABP enhances the interaction of eIFiso4F with the mRNA cap, leading to a rapid, stable complex that serves as a scaffold for initiation complex formation.
Khan et al. (2005) studied this question. eIF4B and PABP vs. eIFiso4F alone was evaluated on Binding rates and conformational changes of mRNA cap analogues. The presence of eIF4B and PABP increased the rate of conformational change by 2.4-fold and slowed dissociation rates by 3.7- to 5.4-fold for mRNA cap analogues binding to eIFiso4F.
