    Decoupling global biases and local interactions between cell biological variables

    Assaf Zaritsky et al.
    DeBias is a generic method to decompose and quantify the confounding, global factors and direct interactions of pairwise interacting variables.

    Guanidine hydrochloride reactivates an ancient septin hetero-oligomer assembly pathway in budding yeast

    Courtney R Johnson et al.
    A naturally-occurring small molecule acts as a chemical chaperone in vivo to alter the folding of a budding yeast septin and promote an oligomerization pathway that was lost during evolution.

    Structural model for differential cap maturation at growing microtubule ends

    Juan Estévez-Gallego et al.
    The tubulin GTPase cycle structurally modulates the microtubule cap, causing lattice expansion, which is an intermediate state involved in phosphate release and regulatory signaling.

    The transpeptidase PBP2 governs initial localization and activity of the major cell-wall synthesis machinery in E. coli

    Gizem Özbaykal et al.
    For initiation of cell-wall insertion, the cross-linking enzyme PBP2 stably binds to a component of the cell envelope that is different from MreB filaments.

    The CHORD protein CHP-1 regulates EGF receptor trafficking and signaling in C. elegans and in human cells

    Andrea Haag et al.
    The co-chaperone CHORDC1 is specifically required for epidermal growth factor receptor trafficking and signaling in Caenorhabditis elegans and in human cells.

    The kinesin-5 tail domain directly modulates the mechanochemical cycle of the motor domain for anti-parallel microtubule sliding

    Tatyana Bodrug et al.
    Biochemical, single molecule, cell and structural biology studies reveal an interaction between the kinesin-5 tail and motor domains regulating high-force production, which is critical for microtubule sliding motility.

    A Fyn biosensor reveals pulsatile, spatially localized kinase activity and signaling crosstalk in live mammalian cells

    Ananya Mukherjee et al.
    Unique biosensor design and protein-engineering enables direct visualization of the active form of Fyn kinase with high specificity, minimal perturbation and shows cellular signaling to be compartmentalized and pulsatile.

    Presenilin/γ-secretase-dependent EphA3 processing mediates axon elongation through non-muscle myosin IIA

    Míriam Javier-Torrent et al.
    EphA signaling plays dual opposite roles on axon dynamics in neurons, so it inhibits and promotes axon growth through ligand binding and receptor processing, respectively.

    A unicellular relative of animals generates a layer of polarized cells by actomyosin-dependent cellularization

    Omaya Dudin et al.
    Cellularization in Sphaeroforma arctica generates a self-organized structure that morphologically resembles an epithelium, and is associated with tightly regulated expression of cell adhesion pathways.
