    Prolonged cross-bridge binding triggers muscle dysfunction in a Drosophila model of myosin-based hypertrophic cardiomyopathy

    William A Kronert et al.
    Integrative analysis of a Drosophila model of hypertrophic cardiomyopathy demonstrates that prolonged binding of the myosin cross-bridge to actin is a root cause of the disorder.

    PPP1R35 is a novel centrosomal protein that regulates centriole length in concert with the microcephaly protein RTTN

    Andrew Michael Sydor et al.
    The previously uncharacterized protein PPP1R35 is a novel centriolar luminal protein critical for centriole elongation by acting in a complex with microcephaly protein RTTN.

    Muscle Contraction: Too much of a good thing

    H Lee Sweeney
    A mutation that causes heart disease in humans increases the number of active myosin heads during contraction in the muscles of fruit flies, leading to the progressive dysfunction of the flight muscles and heart tube.

    Aurora kinase A localises to mitochondria to control organelle dynamics and energy production

    Giulia Bertolin et al.
    AurkA is imported into mitochondria at interphase, and it induces organelle elongation and enhances ATP production when over-expressed.

    Identification of cryptic subunits from an apicomplexan ATP synthase

    Diego Huet et al.
    A phylum-specific ATP synthase subunit is needed for proper mitochondrial function and stability of the complex in Toxoplasma gondii.

    Mitotic progression, arrest, exit or death relies on centromere structural integrity, rather than de novo transcription

    Marco Novais-Cruz et al.
    Direct live-cell imaging of human cells, combined with RNA-seq, qPCR and in vitro reconstitution essays, reveal that mitotic progression, arrest, exit or death is independent of de novo transcription.

    A two-hybrid antibody micropattern assay reveals specific in cis interactions of MHC I heavy chains at the cell surface

    Cindy Dirscherl et al.
    A generally applicable two-hybrid assay demonstrates that MHC class I heavy chains devoid of beta-2 microglobulin associate within and across allotypes, with implications for endocytosis and autoimmunity.

    The adhesion function of the sodium channel beta subunit (β1) contributes to cardiac action potential propagation

    Rengasayee Veeraraghavan et al.
    Structural and functional investigations identify a structural unit for ephaptic coupling in the heart, and provide the mechanistic basis for a novel strategy for the treatment of arrhythmias.

    Tryparedoxin peroxidase-deficiency commits trypanosomes to ferroptosis-type cell death

    Marta Bogacz, R Luise Krauth-Siegel
    Ferroptosis is an evolutionary ancient process that is counterbalanced by distant peroxidases, GPx4 in mammals and tryparedoxin peroxidases in trypanosomes, and can be induced at distinct subcellular membranes depending on the individual cell type.
