    Translational control of one-carbon metabolism underpins ribosomal protein phenotypes in cell division and longevity

    Nairita Maitra et al.
    Extensive molecular profiling shows how loss of highly similar, paralogous ribosomal proteins lead to distinct phenotypic outputs, through translational control of specific mRNAs.

    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.

    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.

    LARP1 functions as a molecular switch for mTORC1-mediated translation of an essential class of mRNAs

    Sungki Hong et al.
    LARP1 turns off and on the translation of an essential class of mRNAs by acting as a key effecter and regulator for mTORC1.

    ME31B globally represses maternal mRNAs by two distinct mechanisms during the Drosophila maternal-to-zygotic transition

    Miranda Wang et al.
    ME31B is a general repressor of gene expression in the Drosophila early embryo, repressing translation before the maternal-to-zygotic transition and stimulating mRNA decay after activation of the zygotic genome.

    Translation repression via modulation of the cytoplasmic poly(A)-binding protein in the inflammatory response

    Xu Zhang et al.
    The RNA-binding protein, Zfp36, which is critical for resolving inflammation, inhibits the production of proinflammatory cytokines via modulation of the cytoplasmic poly(A)-binding protein.

    Establishment of regions of genomic activity during the Drosophila maternal to zygotic transition

    Xiao-Yong Li et al.
    Drosophila melanogaster embryos undergo a dramatic genomic transformation in the hour preceding gastrulation, as thousands of promoters and regulatory regions become biochemically distinct before they become active.

    Translation inhibitory elements from Hoxa3 and Hoxa11 mRNAs use uORFs for translation inhibition

    Fatima Alghoul et al.
    Hoxa3 and Hoxa11 translation inhibitory elements block cap-dependent translation by using upstream open reading frames with distinct modes of action.

    Ribosome collisions trigger cis-acting feedback inhibition of translation initiation

    Szymon Juszkiewicz et al.
    Ribosome collisions along an mRNA are shown to recruit factors that prevent additional ribosomes from initiating translation on that mRNA, thereby providing time to resolve the collision.

    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.
