    Oxidation of cellular amino acid pools leads to cytotoxic mistranslation of the genetic code

    Tammy J Bullwinkle, Noah M Reynolds ... Michael Ibba
    Translation quality control protects the cell from environmental stresses that could potentially lead to the toxic accumulation of non-proteinogenic amino acids in the proteome.

    Quantitative proteomic analysis reveals posttranslational responses to aneuploidy in yeast

    Noah Dephoure, Sunyoung Hwang ... Eduardo M Torres
    Aneuploidy produces a protein expression signature characteristic of altered metabolism and redox homeostasis, and the loss of UBP6 ameliorates several aneuploidy-associated phenotypes.

    Genome-wide regulatory dynamics of translation in the Plasmodium falciparum asexual blood stages

    Florence Caro, Vida Ahyong ... Joseph L DeRisi
    Ribosome profiling has bridged the knowledge gap between transcription and translation during malaria blood stage development and provided a comprehensive gene expression resource for this parasite.

    Global biogeographic sampling of bacterial secondary metabolism

    Zachary Charlop-Powers, Jeremy G Owen ... Sean F Brady
    Pyro-sequencing of two genes involved in bacterial secondary metabolism provides new insights into the rich reservoir of biologically active small molecules found in environmental bacteria.

    Pharmacological dimerization and activation of the exchange factor eIF2B antagonizes the integrated stress response

    Carmela Sidrauski, Jordan C Tsai ... Peter Walter
    A drug-like molecule called ISRIB, which activates the translation initiation factor eIF2B, antagonizes stress responses as diverse as protein misfolding and nutrient deprivation, and restores protein synthesis, enhancing memory.

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

    Marisa D Ruehle, Haibo Zhang ... Jeffrey S Kieft
    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.

    Toxoplasma gondii peptide ligands open the gate of the HLA class I binding groove

    Curtis McMurtrey, Thomas Trolle ... William Hildebrand
    T. gondii infection alters how peptide ligands are presented to the immune system by inducing a previously unreported structural change in Human Leukocyte Antigens (HLAs).

    Structural characterization of ribosome recruitment and translocation by type IV IRES

    Jason Murray, Christos G Savva ... Israel S Fernández
    A Internal Ribosomal Entry Site RNA has been visualised by high resolution cryoEM, trapped in the ribosome in an intermediate state of translocation.
