    Cap-proximal nucleotides via differential eIF4E binding and alternative promoter usage mediate translational response to energy stress

    Ana Tamarkin-Ben-Harush, Jean-Jacques Vasseur ... Rivka Dikstein
    Differential eIF4E binding to transcription initiation nucleotides and alternative promoter usage of eIF1A, PABP and other genes are involved in the response of the translation machinery to energy stress.

    Yeast eIF4A enhances recruitment of mRNAs regardless of their structural complexity

    Paul Yourik, Colin Echeverría Aitken ... Jon R Lorsch
    Eukaryotic translation initiation factor 4A is stimulated by the ribosomal pre-initiation complex and promotes the recruitment of mRNAs regardless of their degree of structure.

    The ribosomal protein Asc1/RACK1 is required for efficient translation of short mRNAs

    Mary K Thompson, Maria F Rojas-Duran ... Wendy V Gilbert
    Asc1/RACK1 promotes the translation of mRNAs associated with the translational closed loop complex, which have short open reading frames and encode proteins required for core metabolic processes.

    Reprogramming of translation in yeast cells impaired for ribosome recycling favors short, efficiently translated mRNAs

    Swati Gaikwad, Fardin Ghobakhlou ... Alan G Hinnebusch
    A mutant impaired for ribosome recycling exhibits translational reprogramming wherein strong mRNAs outcompete weak mRNAs, also observed when preinitiation complexes are diminished by eIF2α phosphorylation or 40S ribosomal subunit depletion.

    Ensemble cryo-EM uncovers inchworm-like translocation of a viral IRES through the ribosome

    Priyanka D Abeyrathne, Cha San Koh ... Andrei A Korostelev
    An ensemble of cryo-EM structures reveals how eukaryotic elongation factor 2 positions the first codon of a viral mRNA for translation.

    Decapping factor Dcp2 controls mRNA abundance and translation to adjust metabolism and filamentation to nutrient availability

    Anil Kumar Vijjamarri, Xiao Niu ... Alan G Hinnebusch
    The yeast mRNA decapping enzyme Dcp1/Dcp2 repressses many genes whose products are required on poor carbon or nitrogen sources in nutrient-replete cells by mRNA decapping and degradation or translational repression, adding post-transcriptional controls to the transcriptional repression of these functions.

    Kinetics of initiating polypeptide elongation in an IRES-dependent system

    Haibo Zhang, Martin Y Ng ... Barry S Cooperman
    The retarding effect of a ribosome-bound internal ribosome entry site on eukaryotic protein synthesis is largely overcome following translocation of tripeptidyl-tRNA.

    A nascent polypeptide sequence modulates DnaA translation elongation in response to nutrient availability

    Michele Felletti, Cédric Romilly ... Kristina Jonas
    Specific amino acids in the N-terminus of the replication initiator protein DnaA inhibit translation elongation upon carbon starvation, illustrating that the identity of the N-terminal amino acids of a protein can modulate protein synthesis yield under changing conditions.

    TASEP modelling provides a parsimonious explanation for the ability of a single uORF to derepress translation during the integrated stress response

    Dmitry E Andreev, Maxim Arnold ... Pavel V Baranov
    A model reveals how translation of an mRNA leader could provide resistance to global downregulation of translation.

    Interface between 40S exit channel protein uS7/Rps5 and eIF2α modulates start codon recognition in vivo

    Jyothsna Visweswaraiah, Alan G Hinnebusch
    The small subunit ribosomal protein uS7/Rps5 interacts with translation initiation factor eIF2α to stabilize first the open, and then the closed conformation of the pre-initiation complex to promote accurate start codon selection in vivo.
