    A mutation uncouples the tubulin conformational and GTPase cycles, revealing allosteric control of microtubule dynamics

    Elisabeth A Geyer et al.
    A buried mutation in αβ-tubulin reveals an allosteric response to GDP in the lattice that dictates microtubule catastrophe and shrinking.

    Inter-dependent apical microtubule and actin dynamics orchestrate centrosome retention and neuronal delamination

    Ioannis Kasioulis et al.
    Microtubules are nucleated by the centrosome of the primary cilium in the apical end-foot of neuroepithelial cells and inter-dependent microtubule and actin dynamics are required here to orchestrate delamination of newborn neurons.

    Kinesin motility is driven by subdomain dynamics

    Wonmuk Hwang et al.
    The motor protein kinesin utilizes its fuel molecule by active and concerted motions of its subdomains, while it rapidly interacts with the microtubule track by forming a wet and dynamic interface.

    Lissencephaly-1 is a context-dependent regulator of the human dynein complex

    Janina Baumbach et al.
    An in vitro reconstitution approach reveals context-dependent roles of Lissencephaly-1 in the regulation of dynein-dynactin behaviour on dynamic microtubules.

    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.

    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.
