    Microtubule reorganization during female meiosis in C. elegans

    Ina Lantzsch et al.
    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.

    The Mitotic Exit Network integrates temporal and spatial signals by distributing regulation across multiple components

    Ian Winsten Campbell et al.
    By distributing regulation to both the GTPase and downstream kinases, the Mitotic Exit Network creates a single signal from spatial and temporal inputs.

    Centrosome age regulates kinetochore–microtubule stability and biases chromosome mis-segregation

    Ivana Gasic et al.
    The presence of cenexin at the old centrosome imposes a functional asymmetry on the mitotic spindle that impacts chromosome alignment and segregation.

    The human SKA complex drives the metaphase-anaphase cell cycle transition by recruiting protein phosphatase 1 to kinetochores

    Sushama Sivakumar et al.
    Microtubule binding by the Spindle and Kinetochore Associated (Ska) complex concentrates protein phosphatase 1 at metaphase kinetochores to overcome the spindle checkpoint thus driving anaphase onset and mitotic exit.

    NuMA recruits dynein activity to microtubule minus-ends at mitosis

    Christina L Hueschen et al.
    At mitosis, NuMA recruits dynein-dynactin to microtubule minus-ends, enabling robust microtubule clustering and the emergence of spindle poles.

    A FRET-based study reveals site-specific regulation of spindle position checkpoint proteins at yeast centrosomes

    Yuliya Gryaznova et al.
    Daughter-cell-associated factors and centrosome-based regulation is important in mitotic exit and spindle position checkpoint control.

    Contractile acto-myosin network on nuclear envelope remnants positions human chromosomes for mitosis

    Alexander JR Booth et al.
    Live-cell imaging shows that the contractile acto-myosin network on the nuclear envelope remnant positions chromosomes in early mitosis to ensure efficient and correct interactions between chromosomes and the mitotic spindle.

    Mechanical design principles of a mitotic spindle

    Jonathan J Ward et al.
    Precise control of microtubule architecture greatly increases the force that the spindle can exert on chromosomes.

    Single-molecule observation of DNA compaction by meiotic protein SYCP3

    Johanna L Syrjänen et al.
    Building on previous work (Syrjänen, Pellegrini, & Davies, 2014), it is shown that SYCP3 contributes to the architecture of meiotic chromosomes through local bridging interactions that result in large-scale compaction of the chromosome axis.

    Activation of Discs large by aPKC aligns the mitotic spindle to the polarity axis during asymmetric cell division

    Ognjen Golub et al.
    The Par complex controls spindle orientation during asymmetric cell division by phosphorylating the tumor suppressor Discs large, overcoming its autoinhibited state, and allowing it to bind the microtubule-binding protein GukHolder.
