    The LIM protein complex establishes a retinal circuitry of visual adaptation by regulating Pax6 α-enhancer activity

    Yeha Kim et al.
    Regulation of Pax6 expression through the α-enhancer fine-tunes amacrine cell subtype number, and consequently, the visual output of the retina.

    Tumor Angiogenesis: Taking aim at Sox18

    Injune Kim, Gou Young Koh
    A small molecule called Sm4 can disrupt interactions involving a transcription factor called Sox18, while having little impact on other members of the SoxF family.

    AMPylation matches BiP activity to client protein load in the endoplasmic reticulum

    Steffen Preissler et al.
    Attaching a molecule of adenosine mono-phosphate (AMP) to the BiP protein at threonine 518 regulates its chaperone activity in the endoplasmic reticulum.

    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.

    Redox signaling via the molecular chaperone BiP protects cells against endoplasmic reticulum-derived oxidative stress

    Jie Wang et al.
    Direct modification by endogenous peroxide of a conserved cysteine in the molecular chaperone BiP decouples its ATPase and peptide-binding activities, allowing for enhanced polypeptide holdase activity during oxidative stress.

    Inadequate BiP availability defines endoplasmic reticulum stress

    Milena Vitale et al.
    The extent of (proteotoxic) endoplasmic reticulum stress, and the ensuing unfolded protein response activation, are commensurate with the extent of the chaperone BiP being sequestered by its client proteins.

    An unexpected role for the yeast nucleotide exchange factor Sil1 as a reductant acting on the molecular chaperone BiP

    Kevin D Siegenthaler et al.
    Building on previous work (Wang et al., 2014), it is shown that the nucleotide exchange factor of the chaperone BiP (Sil1) unexpectedly facilitates the reduction of oxidized BiP.

    Physiological modulation of BiP activity by trans-protomer engagement of the interdomain linker

    Steffen Preissler et al.

    Comprehensive exploration of the translocation, stability and substrate recognition requirements in VIM-2 lactamase

    John Z Chen et al.
    Comprehensive mutational characterisation of VIM-2 metallo-beta-lactamase deciphered the residues responsible for key functional behavior, including translocation, stability, substrate recognition and catalysis.
