    Linker histone H1.8 inhibits chromatin binding of condensins and DNA topoisomerase II to tune chromosome length and individualization

    Pavan Choppakatla, Bastiaan Dekker ... Hironori Funabiki
    Linker histone H1.8 shapes mitotic chromosomes by tuning the number and size of condensin-dependent DNA loops and suppressing condensin and DNA topoisomerase II-dependent individualization.
