Outline of Final Research Achievements |
We showed that miRNA inhibits translation of the target mRNA in a deadenylation- and PABP-independent manner at early time points (PNAS 2012)We next assessed the effect of miRISC on synergistic recruitment of translation initiation factors to target mRNAs by using direct biochemical assays. We show that miRISC promotes the release of both eIF4AI and eIF4AII but not eIF4E and eIF4G from target mRNAs and demonstrate that this is independent of deadenylation. Strikingly, both, the miRISC-induced release of eIF4A I and II from the cap binding complex (CBC) and the miRISC-induced inhibition of cap-dependent translation can be counteracted by the RNA binding protein HuD via a direct interaction of HuD with eIF4A. In summary, we propose that eIF4A I and II are key targets in the translation initiation control mechanisms by miRISC. These results were reported in Molecular Cell (2014).
