    Operon mRNAs are organized into ORF-centric structures that predict translation efficiency

    David H Burkhardt et al.
    Operonic mRNAs in bacteria are comprised of ORF (open reading frame)-wide units of secondary structure, which are intrinsically distinct between adjacent ORFs and encode a rough blueprint for ORF-specific translation efficiency.

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

    Priyanka D Abeyrathne et al.
    An ensemble of cryo-EM structures reveals how eukaryotic elongation factor 2 positions the first codon of a viral mRNA for translation.

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

    Mary K Thompson et al.
    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.

    Eukaryotic translation initiation factor 3 plays distinct roles at the mRNA entry and exit channels of the ribosomal preinitiation complex

    Colin Echeverría Aitken et al.
    Eukaryotic translation initiation factor 3 (eIF3) is required to stabilize the binding of mRNA at the exit channel of the small ribosomal subunit and acts at the entry channel to accelerate mRNA recruitment to the translation preinitiation complex.

    Community effects in regulation of translation

    Paul M Macdonald et al.
    Regulatory elements in an mRNA that act in cis to influence translation can also exert their effects in trans, in a process dependent on assembly of the mRNAs into particles.

    Activation of GCN2 kinase by ribosome stalling links translation elongation with translation initiation

    Ryuta Ishimura et al.
    Activation of the integrated stress response by stalled translation elongation complexes attenuates neurodegeneration, and demonstrates a protective link between a decrease in the rate of translation initiation and defects in translation elongation.

    Poly(A) tail length regulates PABPC1 expression to tune translation in the heart

    Sandip Chorghade et al.
    A poly(A) tail-based regulatory mechanism dynamically controls PABPC1 protein synthesis in cardiomyocytes and thereby titrates cellular translation in response to developmental and hypertrophic cues.

    A dynamic RNA loop in an IRES affects multiple steps of elongation factor-mediated translation initiation

    Marisa D Ruehle et al.
    During initiation factor-independent RNA structure-driven translation initiation, a flexible RNA element drives the movement of a viral IRES through the ribosome's tRNA binding sites and promotes tRNA binding.

    eIF1A residues implicated in cancer stabilize translation preinitiation complexes and favor suboptimal initiation sites in yeast

    Pilar Martin-Marcos et al.
    Substitutions in general translation initiation factor eIF1A found as recurring somatic mutations in uveal melanoma destabilize the closed conformation of the preinitiation complex at the start codon and increase discrimination against suboptimal initiation codons genome-wide.
