Authors: Niladri K Sinha / Alban Ordureau / Katharina Best / James A Saba / Boris Zinshteyn / Elayanambi Sundaramoorthy / Amit Fulzele / Danielle M Garshott / Timo Denk / Matthias Thoms / Joao A ...Authors: Niladri K Sinha / Alban Ordureau / Katharina Best / James A Saba / Boris Zinshteyn / Elayanambi Sundaramoorthy / Amit Fulzele / Danielle M Garshott / Timo Denk / Matthias Thoms / Joao A Paulo / J Wade Harper / Eric J Bennett / Roland Beckmann / Rachel Green / Abstract: Translation of aberrant mRNAs induces ribosomal collisions, thereby triggering pathways for mRNA and nascent peptide degradation and ribosomal rescue. Here we use sucrose gradient fractionation ...Translation of aberrant mRNAs induces ribosomal collisions, thereby triggering pathways for mRNA and nascent peptide degradation and ribosomal rescue. Here we use sucrose gradient fractionation combined with quantitative proteomics to systematically identify proteins associated with collided ribosomes. This approach identified Endothelial differentiation-related factor 1 (EDF1) as a novel protein recruited to collided ribosomes during translational distress. Cryo-electron microscopic analyses of EDF1 and its yeast homolog Mbf1 revealed a conserved 40S ribosomal subunit binding site at the mRNA entry channel near the collision interface. EDF1 recruits the translational repressors GIGYF2 and EIF4E2 to collided ribosomes to initiate a negative-feedback loop that prevents new ribosomes from translating defective mRNAs. Further, EDF1 regulates an immediate-early transcriptional response to ribosomal collisions. Our results uncover mechanisms through which EDF1 coordinates multiple responses of the ribosome-mediated quality control pathway and provide novel insights into the intersection of ribosome-mediated quality control with global transcriptional regulation. | ||||||||||||
