    Cohesin-interacting protein WAPL-1 regulates meiotic chromosome structure and cohesion by antagonizing specific cohesin complexes

    Oliver Crawley et al.
    By specifically antagonizing binding of complexes carrying COH-3/4 kleisins, WAPL-1 regulates chromosome structure and cohesion throughout meiotic prophase.

    Local chromosome context is a major determinant of crossover pathway biochemistry during budding yeast meiosis

    Darpan Medhi et al.
    Different homologous recombination pathways are dominant in different regions of meiotic chromosomes, indicating that chromosome structure influences recombination biochemistry.

    A molecular model for the role of SYCP3 in meiotic chromosome organisation

    Johanna Liinamaria Syrjänen et al.
    A structural and biochemical study of human SYCP3 provides the first molecular model for the three-dimensional organisation that is imposed upon chromosomal DNA during meiosis and is essential for genetic exchange and fertility.

    Metaphase chromosome structure is dynamically maintained by condensin I-directed DNA (de)catenation

    Ewa Piskadlo et al.
    Condensin I maintains chromosome organization throughout metaphase by preventing erroneous topoisomerase II-dependent sister chromatid re-entanglements.

    A conserved filamentous assembly underlies the structure of the meiotic chromosome axis

    Alan MV West et al.
    Meiotic chromosome axis 'core' proteins from fungi, plants, and mammals form a conserved filament architecture, and use a common mechanism to recruit HORMAD proteins for meiotic recombination control.

    The ATPases of cohesin interface with regulators to modulate cohesin-mediated DNA tethering

    Gamze Çamdere et al.
    A critical second step in DNA tethering by cohesin occurs after its stable binding to DNA, and this second step is modulated by the Smc3 ATPase active site in Saccharomyces cerevisiae.

    Aurora-A mediated histone H3 phosphorylation of threonine 118 controls condensin I and cohesin occupancy in mitosis

    Candice L Wike et al.
    A histone modification that alters the nucleosome structure occurs in mitosis and promotes chromosome packaging and the timely removal of condensin I and cohesion, to achieve chromosome segregation.

    Mitotic spindle scaling during Xenopus development by kif2a and importin α

    Jeremy D Wilbur, Rebecca Heald
    An interaction between two proteins enables the spindle—the structure that segregates chromosome pairs during mitosis—to change size as cells divide.

    Convergence of topological domain boundaries, insulators, and polytene interbands revealed by high-resolution mapping of chromatin contacts in the early Drosophila melanogaster embryo

    Michael R Stadler et al.
    Fruit fly chromosomes are divided into discrete structural domains by regions of decompacted chromatin, suggesting a novel model for the formation of a known class of genetic elements.

    MukB ATPases are regulated independently by the N- and C-terminal domains of MukF kleisin

    Katarzyna Zawadzka et al.
    In Escherichia coli structural maintenance of chromosomes (SMC) complex, MukBEF, a dimeric MukF kleisin binds and activates MukB SMC ATPases through two independent interfaces provided by distinct MukF N- and C-terminal domains.
