    Reconstitution of dynein transport to the microtubule plus end by kinesin

    Anthony J Roberts, Brian S Goodman, Samara L Reck-Peterson
    In vitro reconstitution reveals how a system of molecules works together to transport the motor protein dynein to the start of its track.

    Mechanics and kinetics of dynamic instability

    Thomas CT Michaels, Shuo Feng ... L Mahadevan
    A theoretical framework for the growth of microtubules quantifies the roles of geometry, mechanics, kinetics and randomness and provides a phase diagram for dynamic instability in these self-assembled polymers.

    Microtubule rescue at midzone edges promotes overlap stability and prevents spindle collapse during anaphase B

    Manuel Lera-Ramirez, François J Nédélec, Phong T Tran
    A simple mechanism relying on microtubule rescues occurring at midzone edges allows fission yeast spindles to elongate during anaphase B while maintaining microtubule overlaps, without the need to precisely regulate microtubule growth speed.

    Microtubule reorganization during female meiosis in C. elegans

    Ina Lantzsch, Che-Hang Yu ... Stefanie Redemann
    Structural rearrangements of meiotic spindles during the transition from metaphase to anaphase can be controlled by local changes of microtubule dynamics, such as nucleation and/or turnover, and that katanin promotes microtubule turnover by severing microtubules near the chromosomes.

    Nuclear SUN1 stabilizes endothelial cell junctions via microtubules to regulate blood vessel formation

    Danielle B Buglak, Pauline Bougaran ... Victoria L Bautch
    The nuclear membrane protein SUN1 stabilizes endothelial cell-cell junctions far from the nucleus via regulation of microtubule dynamics and Rho GEF-H1 signaling, revealing long-range cellular communication important for vascular development and function.

    The integrated stress response remodels the microtubule-organizing center to clear unfolded proteins following proteotoxic stress

    Brian Hurwitz, Nicola Guzzi ... Elaine Fuchs
    In response to proteotoxic stress, squamous cell carcinoma cells hijack the integrated stress response to promote recovery by bolstering protection of microtubule dynamics.

    Microtubule assembly governed by tubulin allosteric gain in flexibility and lattice induced fit

    Maxim Igaev, Helmut Grubmüller
    A new combined mechanism explains how GTP binding by tubulin is linked to its dynamics and energetics in solution and why GTP-induced flexibility, and not the tubulin conformation as such, drives microtubule assembly.

    Microneedle manipulation of the mammalian spindle reveals specialized, short-lived reinforcement near chromosomes

    Pooja Suresh, Alexandra F Long, Sophie Dumont
    Directly exerting force on the mammalian spindle reveals local and short-lived reinforcement in the spindle center, well-suited to preserve connections to chromosomes over seconds and yet allow remodeling over minutes.

    Kinesin Kip2 enhances microtubule growth in vitro through length-dependent feedback on polymerization and catastrophe

    Anneke Hibbel, Aliona Bogdanova ... Jonathon Howard
    The budding yeast kinesin Kip2 is a polymerase that uses its processive motility in a positive feedback loop to promote microtubule growth.

    Synergistic stabilization of microtubules by BUB-1, HCP-1, and CLS-2 controls microtubule pausing and meiotic spindle assembly

    Nicolas Macaisne, Laura Bellutti ... Julien Dumont
    Promotion of microtubule pausing by a kinetochore module controls meiotic spindle assembly in Caenorhabditis elegans oocytes.
