    Unraveling the influences of sequence and position on yeast uORF activity using massively parallel reporter systems and machine learning

    Gemma E May, Christina Akirtava ... Joel McManus
    The regulatory role of thousands of upstream open-reading frames were measured and used to determine the relative influences of sequence, structural, and positional features on translation regulation and nonsense-mediated decay.

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

    Fatima Alghoul, Schaeffer Laure ... Franck Martin
    Hoxa3 and Hoxa11 translation inhibitory elements block cap-dependent translation by using upstream open reading frames with distinct modes of action.

    TASEP modelling provides a parsimonious explanation for the ability of a single uORF to derepress translation during the integrated stress response

    Dmitry E Andreev, Maxim Arnold ... Pavel V Baranov
    A model reveals how translation of an mRNA leader could provide resistance to global downregulation of translation.

    Regulatory roles of Escherichia coli 5' UTR and ORF-internal RNAs detected by 3' end mapping

    Philip P Adams, Gabriele Baniulyte ... Joseph T Wade
    Multiple RNA-seq approaches globally mapped RNA 3´ ends resulting in the discovery of numerous and diverse RNA regulators.

    Operon mRNAs are organized into ORF-centric structures that predict translation efficiency

    David H Burkhardt, Silvi Rouskin ... Carol A Gross
    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.

    Yeast eIF2A has a minimal role in translation initiation and uORF-mediated translational control in vivo

    Swati Gaikwad, Fardin Ghobakhlou ... Alan G Hinnebusch
    Eliminating eukaryotic initiation factor 2 (eIF2) from wild-type budding yeast had little impact on translation of individual mRNAs, including those with regulatory upstream open-reading frames, even when canonical initiation factor eIF2 activity was impaired.

    Translation of 5′ leaders is pervasive in genes resistant to eIF2 repression

    Dmitry E Andreev, Patrick BF O'Connor ... Pavel V Baranov
    Most of the mRNAs whose translation is resistant to the stress-induced repression of protein synthesis contain upstream open reading frames that are efficiently translated under normal conditions.

    Comprehensive annotations of human herpesvirus 6A and 6B genomes reveal novel and conserved genomic features

    Yaara Finkel, Dominik Schmiedel ... Noam Stern-Ginossar
    Unbiased mapping of viral open reading frames (ORFs) and transcripts in HHV-6 genomes uncovers novel ORFs and lncRNAs that are conserved across betaherpesviruses.

    The small molecule ISRIB reverses the effects of eIF2α phosphorylation on translation and stress granule assembly

    Carmela Sidrauski, Anna M McGeachy ... Peter Walter
    Building on previous work which showed that the small molecule ISRIB potently blocks the integrated stress response (Sidrauski et al., 2013), we report on ISRIB's remarkable specificity and fast action in vivo, underscoring its proposed direct effect on translation.
