    VASP-mediated actin dynamics activate and recruit a filopodia myosin

    Ashley L Arthur, Amy Crawford ... Margaret A Titus
    Filopodia formation requires recruitment and activation of myosin through generation of parallel, bundled actin filaments by VASP polymerase, revealing coupling between motor activation and organization of a local actin network.

    Galectin-9 regulates the threshold of B cell activation and autoimmunity

    Logan K Smith, Kareem Fawaz, Bebhinn Treanor
    Galectin-9-deficient mice develop spontaneous autoimmunity, driven by a decreased threshold of B cell activation and enhanced auto-antigen delivery to the spleen by increased B1a-derived autoantibodies.

    Cdc4 phospho-degrons allow differential regulation of Ame1CENP-U protein stability across the cell cycle

    Miriam Böhm, Kerstin Killinger ... Stefan Westermann
    The cell cycle machinery regulates the assembly of the multi-protein kinetochore complex by targeting excess subunits for degradation via the proteasome.

    SOX21 modulates SOX2-initiated differentiation of epithelial cells in the extrapulmonary airways

    Evelien Eenjes, Marjon Buscop-van Kempen ... Robbert J Rottier
    The balance between SOX2 and SOX21 is evolutionary conserved and is important for cell fate decision during lung epithelium development and repair after damage.

    Novel LOTUS-domain proteins are organizational hubs that recruit C. elegans Vasa to germ granules

    Patricia Giselle Cipriani, Olivia Bay ... Kristin C Gunsalus
    Two novel LOTUS-domain proteins are core germ granule components that directly recruit Caenorhabditis elegans Vasa, regulate germ granule size and localization, and provide an organizational framework for ribonucleoprotein complexes.

    Pharmacological rescue of impaired mitophagy in Parkinson’s disease-related LRRK2 G2019S knock-in mice

    Francois Singh, Alan R Prescott ... Ian G Ganley
    The most common Parkinson’s disease-associated mutation, LRRK2 G2019S, impairs mitophagy in clinically relevant cells within the mouse brain and this defect can be reversed using a novel LRRK2 inhibitor.

    Different translation dynamics of β- and γ-actin regulates cell migration

    Pavan Vedula, Satoshi Kurosaka ... Anna Kashina
    β- and γ-cytoplasmic actins have different translation rates in cells and exert different nucleotide coding sequence-dependent effects on cell migration.

    Role of BRCA2 DNA-binding and C-terminal domain in its mobility and conformation in DNA repair

    Maarten W Paul, Arshdeep Sidhu ... Claire Wyman
    Highly conserved C-terminal domains of the tumor suppressor BRCA2 are not essential for accumulation at damaged DNA but affect conformation and cell survival, implying roles beyond delivering strand-exchange protein RAD51.
