    Peroxisomal lactate dehydrogenase is generated by translational readthrough in mammals

    Fabian Schueren, Thomas Lingner ... Sven Thoms
    Whole-genome in silico screening for stop codon contexts that produce elevated translational readthrough and peroxisome targeting reveals that in mammals, the amount of lactate dehydrogenase in the peroxisome is controlled by translational readthrough.

    Ribosome profiling reveals pervasive and regulated stop codon readthrough in Drosophila melanogaster

    Joshua G Dunn, Catherine K Foo ... Jonathan S Weissman
    Ribosomes translate through stop codons far more often than previously thought, yielding C-terminally extended proteins in a variety of eukaryotes.

    Stop codon context influences genome-wide stimulation of termination codon readthrough by aminoglycosides

    Jamie R Wangen, Rachel Green
    Ribosome profiling reveals genome-wide stimulation of stop codon readthrough by aminoglycosides that is influenced sequence context.

    A concerted increase in readthrough and intron retention drives transposon expression during aging and senescence

    Kamil Pabis, Diogo Barardo ... Brian K Kennedy
    A majority of transcribed transposons during aging are derived from transcriptional defects, most notably intron retention and transcriptional readthrough.

    A plant-like mechanism coupling m6A reading to polyadenylation safeguards transcriptome integrity and developmental gene partitioning in Toxoplasma

    Dayana C Farhat, Matthew W Bowler ... Christopher Swale
    The epitranscriptomic-driven mRNA polyadenylation pathway protects transcriptome integrity by restricting transcriptional read-throughs and RNA chimera formation in apicomplexan parasites and plants.

    A new ‘CFS tracking’ paradigm reveals uniform suppression depth regardless of target complexity or salience

    David Alais, Jacob Coorey ... Matthew J Davidson
    A new and efficient continuous flash suppression (CFS) method is presented that provides breakthrough and suppression thresholds to quantify depth of target suppression.

    The nucleosome DNA entry-exit site is important for transcription termination and prevention of pervasive transcription

    A Elizabeth Hildreth, Mitchell A Ellison ... Karen M Arndt
    Disruption of the nucleosome DNA entry-exit site causes readthrough transcription of terminators, decreased nucleosome occupancy, and pervasive noncoding transcription, demonstrating this nucleosomal region protects the genome against inappropriate transcription.

    Translation: Finding sense in the context

    Kim M Keeling, David M Bedwell
    Ribosomal profiling has shed new light on how ribosomes can ignore stop codons in messenger RNA.

    Genome-wide effects of the antimicrobial peptide apidaecin on translation termination in bacteria

    Kyle Mangano, Tanja Florin ... Nora Vázquez-Laslop
    Inhibition of bacterial protein synthesis by an antimicrobial peptide apidaecin triggers translation arrest at the stop codons, ribosome queuing and pervasive stop codon readthrough.
