    The force-sensing peptide VemP employs extreme compaction and secondary structure formation to induce ribosomal stalling

    Ting Su et al.
    The structure of the VemP-stalled ribosome reveals a helix-double turn-helix conformation of the nascent chain within the ribosomal tunnel, illustrating how secondary structure formation directly at the peptidyltransferase center of the ribosome can induce translational arrest.

    Ribosomal mutations promote the evolution of antibiotic resistance in a multidrug environment

    James E Gomez et al.
    Mutations in several components of a bacterial ribosome are shown to broadly decrease antibiotic and stress sensitivity, and readily accessible reversion mutations allow these ribosomal mutations to serve as stepping stones to high level antibiotic resistance.

    Spatial sequestration and detoxification of Huntingtin by the ribosome quality control complex

    Junsheng Yang et al.
    A genome-wide screen in yeast reveals that key proteins in ribosome quality control also regulate mutant Huntingtin aggregation and toxicity.

    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.

    Mechanisms of ribosome stalling by SecM at multiple elongation steps

    Jun Zhang et al.
    Nascent regulatory peptides tune the translation rate through a continuous, dynamic reshaping of the functional center of the ribosome.

    A RanGTP-independent mechanism allows ribosomal protein nuclear import for ribosome assembly

    Sabina Schütz et al.
    The Tsr2 carrier protein connects the nuclear import machinery with the ribosome assembly pathway.

    A systematically-revised ribosome profiling method for bacteria reveals pauses at single-codon resolution

    Fuad Mohammad et al.
    With the removal of confounding artifacts, ribosome profiling can yield insight into the mechanism of protein synthesis in bacteria at high resolution.

    Proteotoxicity from aberrant ribosome biogenesis compromises cell fitness

    Blake W Tye et al.
    Rapidly proliferating cells are at risk of compromised cell fitness due to proteostasis collapse from perturbations that interfere with ribosome biogenesis.

    Multi-protein bridging factor 1(Mbf1), Rps3 and Asc1 prevent stalled ribosomes from frameshifting

    Jiyu Wang et al.
    An eukaryotic specific system cooperates with the ribosome quality control pathway to maintain the reading frame during translation of slowly translated sequences.
