    Unstructured regions in IRE1α specify BiP-mediated destabilisation of the luminal domain dimer and repression of the UPR

    Niko Amin-Wetzel et al.
    Client protein-driven reversal of endoplasmic reticulum chaperone (BiP) mediated-repression is revealed as a principal component of the regulation of the unfolded protein response transducer IRE1 in cells.

    Vasohibin1, a new mouse cardiomyocyte IRES trans-acting factor that regulates translation in early hypoxia

    Fransky Hantelys et al.
    In mouse cardiomyocytes, (lymph)angiogenic growth factors are induced during early hypoxia by a translational mechanism involving a new IRES trans-acting factor, vasohibin-1.

    A complex IRES at the 5'-UTR of a viral mRNA assembles a functional 48S complex via an uAUG intermediate

    Ritam Neupane et al.
    The ribosome bound structure of a new IRES reveals novel architecture features used by viruses to hijack cellular translation.

    An unfolded protein-induced conformational switch activates mammalian IRE1

    G Elif Karagöz et al.
    ER-stress sensing mechanism of the unfolded protein response sensor/transducer IRE1 is conserved from yeast to mammals, where in mammals, unfolded protein binding to IRE1's ER lumenal domain is coupled to its oligomerization and activation through an allosteric conformational change.

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

    Marisa D Ruehle et al.
    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.

    Transdifferentiation mediated tumor suppression by the endoplasmic reticulum stress sensor IRE-1 in C. elegans

    Mor Levi-Ferber et al.
    IRE-1 manipulates tumor cell identity to restore apoptosis sensitivity and suppress an aggressive germline tumor in C. elegans.

    Ensemble cryo-EM uncovers inchworm-like translocation of a viral IRES through the ribosome

    Priyanka D Abeyrathne et al.
    An ensemble of cryo-EM structures reveals how eukaryotic elongation factor 2 positions the first codon of a viral mRNA for translation.

    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.

    Kinetics of initiating polypeptide elongation in an IRES-dependent system

    Haibo Zhang et al.
    The retarding effect of a ribosome-bound internal ribosome entry site on eukaryotic protein synthesis is largely overcome following translocation of tripeptidyl-tRNA.
