    Noncanonical binding of BiP ATPase domain to Ire1 and Perk is dissociated by unfolded protein CH1 to initiate ER stress signaling

    Marta Carrara et al.
    The chaperone protein BiP forms complexes with Ire1 and Perk that dissociate when unfolded proteins bind to BiP to activate the unfolded protein response in the ER.

    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.

    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.

    The insulin receptor cellular IRES confers resistance to eIF4A inhibition

    Calla M Olson et al.
    Utilizing a conserved mechanism, a ribosome can initiate translation from a site within the insulin receptor mRNA to maintain protein synthesis even when standard mechanisms of initiating translation have been inhibited by stress.

    ERα promotes murine hematopoietic regeneration through the Ire1α-mediated unfolded protein response

    Richard H Chapple et al.
    Estrogen is a systemic factor that promotes hematopoietic regeneration by activating the unfolded protein responses.

    Structural characterization of ribosome recruitment and translocation by type IV IRES

    Jason Murray et al.
    A Internal Ribosomal Entry Site RNA has been visualised by high resolution cryoEM, trapped in the ribosome in an intermediate state of translocation.

    Unfolded protein response transducer IRE1-mediated signaling independent of XBP1 mRNA splicing is not required for growth and development of medaka fish

    Tokiro Ishikawa et al.
    The unfolded protein response sensor/transducer IRE1-mediated splicing of XBP1 mRNA encoding its active downstream transcription factor to maintain the homeostasis of the endoplasmic reticulum is sufficient for growth and development of medaka fish.

    E3 ubiquitin ligase Bre1 couples sister chromatid cohesion establishment to DNA replication in Saccharomyces cerevisiae

    Wei Zhang et al.
    E3 ubiquitin ligase Bre1-induced H2B monoubiquitination is epigenetically important for recruiting replication factor Mcm10 and cohesion establishment factors Ctf4, Ctf18 and Eco1 to early replication origins to establish sister chromatid cohesion.

    Caspase-mediated cleavage of IRE1 controls apoptotic cell commitment during endoplasmic reticulum stress

    Anna Shemorry et al.
    Biochemical and biological studies reveal that caspases feed back onto the Unfolded Protein Response by cleaving the ER-stress sensor IRE1 to produce a cytoprotective N-terminal fragment that inhibits BAX-dependent apoptosis.

    Dual tRNA mimicry in the Cricket Paralysis Virus IRES uncovers an unexpected similarity with the Hepatitis C Virus IRES

    Vera P Pisareva et al.
    A conformational change in the Cricket Paralysis Virus IRES upon double translocation in the ribosome uncovers an unexpected similarity with the Hepatitis C Virus IRES.
