    The KASH5 protein involved in meiotic chromosomal movements is a novel dynein activating adaptor

    Ritvija Agrawal, John P Gillies ... Morgan E DeSantis
    KASH5 uses an EF-hand domain to directly interact with the light intermediate chain of dynein, promotes processive dynein motility, and facilitates dynein recruitment to the nuclear envelope during prophase I of meiosis.

    Tonic inhibition of the chloride/proton antiporter ClC-7 by PI(3,5)P2 is crucial for lysosomal pH maintenance

    Xavier Leray, Jacob K Hilton ... Joseph A Mindell
    Inhibiyiton of the lysosomal chloride-proton antiporter ClC-7 by the signaling lipid PI(3,5)P2 is important for lysosomal pH maintenance and is disrupted by a disease-causing gain-of-function mutation.

    Endoplasmic reticulum stress activates human IRE1α through reversible assembly of inactive dimers into small oligomers

    Vladislav Belyy, Iratxe Zuazo-Gaztelu ... Peter Walter
    Stress sensors in the membrane of the endoplasmic reticulum respond to the accumulation of unfolded proteins by briefly forming small phosphorylation-competent oligomers and dissolving back into active dimers.

    Distinctive mechanisms of epilepsy-causing mutants discovered by measuring S4 movement in KCNQ2 channels

    Michaela A Edmond, Andy Hinojo-Perez ... Rene Barro-Soria
    Because voltage-gated KCNQ2 channels are central to physiological and pathophysiological events, understanding how disease-causing mutations in different channel regions disrupt function will help future development of mutation-specific antiepileptic therapies.
