    Measuring NDC80 binding reveals the molecular basis of tension-dependent kinetochore-microtubule attachments

    Tae Yeon Yoo, Jeong-Mo Choi ... Daniel J Needleman
    Quantitative experiments and theory show that the tension-dependent regulation of NDC80 binding to kinetochore microtubules arises from a combination of the changing Aurora B concentration at NDC80 and the nonlinearity of Aurora B autoactivation.

    Self-organization of kinetochore-fibers in human mitotic spindles

    William Conway, Robert Kiewisz ... Daniel J Needleman
    A biophysical model in which kinetochore microtubules nucleate at kinetochores and growth polward along nematic streamlines quantitatively explains kinetochore microtubule lengths, orientations, and spatially varying dynamics in metaphase human spindles.

    The kinetochore prevents centromere-proximal crossover recombination during meiosis

    Nadine Vincenten, Lisa-Marie Kuhl ... Adèle L Marston
    The meiotic DNA recombination landscape is locally influenced by the kinetochore to minimize potentially deleterious pericentromeric crossover recombination.

    Augmin prevents merotelic attachments by promoting proper arrangement of bridging and kinetochore fibers

    Valentina Štimac, Isabella Koprivec ... Iva M Tolić
    STED microscopy of human mitotic spindles reveals how augmin-nucleated microtubules protect the cell from erroneous kinetochore-microtubule attachments and ensure a highly organized architecture of the spindle required for mitotic fidelity.

    Human kinetochores are swivel joints that mediate microtubule attachments

    Chris A Smith, Andrew D McAinsh, Nigel J Burroughs
    The outer domain of the kinetochore can rotate (swivel) around the centromere, and this rather than intra-kinetochore stretching is coupled to anaphase onset.

    Division of labour between PP2A-B56 isoforms at the centromere and kinetochore

    Giulia Vallardi, Lindsey A Allan ... Adrian T Saurin
    Distinct PP2A-B56 complexes use isoform-selective interactions to localise to either the centromere or kinetochore and control different processes during mitosis.

    Meiosis I chromosome segregation is established through regulation of microtubule–kinetochore interactions

    Matthew P Miller, Elçin Ünal ... Angelika Amon
    Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.

    The pseudo GTPase CENP-M drives human kinetochore assembly

    Federica Basilico, Stefano Maffini ... Andrea Musacchio
    Centromeric protein M (CENP-M) is required for the stabilization of a quaternary complex that plays a crucial role in kinetochore organization and function.

    Multivalency of NDC80 in the outer kinetochore is essential to track shortening microtubules and generate forces

    Vladimir A Volkov, Pim J Huis in 't Veld ... Andrea Musacchio
    Multiple NDC80 complexes in the outer kinetochore cooperate to bind the ends of depolymerizing microtubules and harness their power stroke.

    Sister kinetochore splitting and precocious disintegration of bivalents could explain the maternal age effect

    Agata P Zielinska, Zuzana Holubcova ... Melina Schuh
    Multiple age-related changes in chromosome architecture could explain why human oocyte aneuploidy increases with advanced maternal age.
