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

    Ritvija Agrawal et al.
    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 et al.
    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.

    Hypoxia controls plasma membrane targeting of polarity proteins by dynamic turnover of PI4P and PI(4,5)P2

    Juan Lu et al.
    When challenged by energetic stresses triggered by hypoxia and ATP inhibition, plasma membrane PI4P and PIP2 in cells undergo dramatic turnovers that have profound impact on many cellular processes including electrostatic PM targeting of numerous polybasic proteins.

    Sequence and structural conservation reveal fingerprint residues in TRP channels

    Deny Cabezas-Bratesco et al.
    Joint sequence, structure, and phylogenetic analyses identify highly conserved features in transmembrane domains of transient receptor potential (TRP) ion channel proteins that offer a novel explanation for how TRPs could integrate stimuli into cellular signals.

    Waveform detection by deep learning reveals multi-area spindles that are selectively modulated by memory load

    Maryam H Mofrad et al.
    A new computational approach for detecting sleep waveforms reveals that the 11–15 Hz sleep 'spindle', a neural rhythm implicated in memory consolidation, co-occurs widely across cortex much more often than previously thought.

    Hypertrophic cardiomyopathy mutations in the pliant and light chain-binding regions of the lever arm of human β-cardiac myosin have divergent effects on myosin function

    Makenna M Morck et al.
    Hypertrophic cardiomyopathy-causing mutations in the light chain-binding region of β-cardiac myosin's lever arm appear to disrupt myosin tail-based autoinhibition, while mutations in the pliant region of the lever arm reduce autoinhibition in the presence of actin and impact myosin’s powerstroke.

    An expanded toolkit for Drosophila gene tagging using synthesized homology donor constructs for CRISPR-mediated homologous recombination

    Oguz Kanca et al.
    New construct designs and gene targeting strategies from the Gene Disruption Project allow efficient tagging of almost all Drosophila genes.

    All-atom molecular dynamics simulations of Synaptotagmin-SNARE-complexin complexes bridging a vesicle and a flat lipid bilayer

    Josep Rizo et al.
    Novel insights into the molecular mechanisms underlying neurotransmitter release are provided by all-atom molecular dynamics simulations including SNARE proteins, synaptotagmin-1, complexin-1, a vesicle and a flat bilayer.
