    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.

    Chromosome mis-segregation and cytokinesis failure in trisomic human cells

    Joshua M Nicholson, Joana C Macedo ... Daniela Cimini
    Aneuploidy can cause chromosome mis-segregation and specific cellular phenotypes driven by expression of genes on the extra chromosome.

    Depletion or cleavage of cohesin during anaphase differentially affects chromatin structure and segregation

    Jonay Garcia-Luis, Hélène Bordelet ... Luis Aragon
    Cohesin role in chromosome organisation during anaphase is necessary for the segregation of chromosomes.

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

    Ivana Gasic, Purnima Nerurkar, Patrick Meraldi
    The presence of cenexin at the old centrosome imposes a functional asymmetry on the mitotic spindle that impacts chromosome alignment and segregation.

    Splicing factors Sf3A2 and Prp31 have direct roles in mitotic chromosome segregation

    Claudia Pellacani, Elisabetta Bucciarelli ... Maria Patrizia Somma
    Extensive cytological and biochemical analyses show that the conserved Sf3A2 and Prp31 splicing factors bind microtubules and the Ndc80 complex, playing direct mitotic functions in both Drosophila and human mitosis.

    Kinetochores attached to microtubule-ends are stabilised by Astrin bound PP1 to ensure proper chromosome segregation

    Duccio Conti, Parveen Gul ... Viji M Draviam
    Human chromosome-microtubule attachments are stabilised by Astrin-mediated dynamic delivery of PP1 phosphatase to the attachment site, which ensures the normal segregation of chromosomes.

    Evidence for a DNA-relay mechanism in ParABS-mediated chromosome segregation

    Hoong Chuin Lim, Ivan Vladimirovich Surovtsev ... Christine Jacobs-Wagner
    In vitro, in vivo and in silico evidence suggests that bacteria exploit intrinsic chromosomal fluctuations to achieve intracellular transport.

    Banp regulates DNA damage response and chromosome segregation during the cell cycle in zebrafish retina

    Swathy Babu, Yuki Takeuchi, Ichiro Masai
    Banp is a transcription activator of cell cycle genes like cenpt, ncapg, and wrnip1 to prevent genotoxic stress during rapid cell division and its repercussions on development and disease.

    Kinetochore-independent chromosome segregation driven by lateral microtubule bundles

    Christina C Muscat, Keila M Torre-Santiago ... Sarah M Wignall
    Chromosomes in C. elegans female reproductive cells segregate through motor-driven movement along lateral microtubule bundles.

    Pathogenic mutations in the chromokinesin KIF22 disrupt anaphase chromosome segregation

    Alex F Thompson, Patrick R Blackburn ... Jason Stumpff
    Pathogenic mutations in KIF22, which dominantly cause bone dysplasia, improperly activate the motor during anaphase in dividing cells leading to chromosome recongression.
