    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.

    Ribosome biogenesis restricts innate immune responses to virus infection and DNA

    Christopher Bianco, Ian Mohr
    Ribosome production is unexpectedly integrated into innate cell-intrinsic responses that regulate double strand DNA-sensing and inflammatory cytokine induction in infected and uninfected cells.

    Sequence specific detection of bacterial 23S ribosomal RNA by TLR13

    Xiao-Dong Li, Zhijian J Chen
    A pattern recognition receptor called toll-like receptor 13 detects pathogens in a manner that is different to that seen in other pathogen sensors.

    LARP4 mRNA codon-tRNA match contributes to LARP4 activity for ribosomal protein mRNA poly(A) tail length protection

    Sandy Mattijssen et al.
    The messenger RNA encoding La-related protein-4 (LARP4) contains a short region of instability whose codon clusters are sensitive to low abundance tRNAs that when elevated increase LARP4 activity for poly(A) lengthening of ribosomal protein mRNAs and other mRNAs.

    Autophagy-dependent ribosomal RNA degradation is essential for maintaining nucleotide homeostasis during C. elegans development

    Yubing Liu et al.
    Embryonic development requires autophagy-dependent degradation of ribosomal RNAs.

    Distinct stages of the translation elongation cycle revealed by sequencing ribosome-protected mRNA fragments

    Liana F Lareau et al.
    The size of the mRNA fragment protected by a ribosome depends on the ribosome's conformation, which enables studies of the distinct steps of decoding and translocation at single-codon resolution.

    Ribosome•RelA structures reveal the mechanism of stringent response activation

    Anna B Loveland et al.
    Cryo-EM structures of 70S•RelA ribosome complexes reveal how cognate deacyl-tRNA activates RelA.

    Regulated Ire1-dependent mRNA decay requires no-go mRNA degradation to maintain endoplasmic reticulum homeostasis in S. pombe

    Nicholas R Guydosh et al.
    A critical component of the cellular response to unfolded proteins is the widespread rescue of ribosomes that stall on endonucleolytically-cleaved mRNA transcripts.

    Conformational switches control early maturation of the eukaryotic small ribosomal subunit

    Mirjam Hunziker et al.
    Mass spectrometry analysis of purified pre-ribosomal RNAs shows that stable ribosomal RNA domains independently recruit assembly factors, and the cryo-EM structure of the 5' ETS ribonucleoprotein reveals regulatory conformational switches.

    A single H/ACA small nucleolar RNA mediates tumor suppression downstream of oncogenic RAS

    Mary McMahon et al.
    Cancer-associated changes in small nucleolar RNAs and site-specific pseudouridine modifications impact ribosome activity.
