    Asymmetry between the two acidic patches dictates the direction of nucleosome sliding by the ISWI chromatin remodeler

    Robert F Levendosky, Gregory D Bowman
    Unlike Chd1, ISWI remodelers preferentially shift asymmetric nucleosomes toward the side possessing a wild type acidic patch, regardless of DNA lengths flanking the nucleosome.

    Nucleosome-CHD4 chromatin remodeler structure maps human disease mutations

    Lucas Farnung, Moritz Ochmann, Patrick Cramer
    The structure of the chromatin remodeller CHD4 bound to a nucleosome reveals differences to the known Chd1-nucleosome complex and maps cancer mutations.

    The nucleosomal acidic patch relieves auto-inhibition by the ISWI remodeler SNF2h

    Nathan Gamarra, Stephanie L Johnson ... Geeta J Narlikar
    Auto-inhibition of ISWI-family ATP-dependent chromatin remodelers is relieved by a conserved feature of the nucleosome.

    Architecture of the chromatin remodeler RSC and insights into its nucleosome engagement

    Avinash B Patel, Camille M Moore ... Eva Nogales
    The structure of the yeast RSC complex, a member of the SWI/SNF chromatin remodeling family, determined by cryo-electron microscopy, reveals a conserved structural core and the mode of nucleosome engagement.

    Specialization of the chromatin remodeler RSC to mobilize partially-unwrapped nucleosomes

    Alisha Schlichter, Margaret M Kasten ... Bradley R Cairns
    A SWI/SNF-family chromatin remodeling subcomplex from yeast is identified (RSC1) that is specialized to slide nucleosomes residing on DNA sequences that confer partial nucleosome unwrapping, with assistance from accessory factors.

    Nucleosome breathing and remodeling constrain CRISPR-Cas9 function

    R Stefan Isaac, Fuguo Jiang ... Ricardo Almeida
    The inhibitory influence of nucleosomes on CRISPR-Cas9 is mitigated by nucleosomal DNA breathing and chromatin remodeling.

    The chromatin remodelers RSC and ISW1 display functional and chromatin-based promoter antagonism

    Timothy J Parnell, Alisha Schlichter ... Bradley R Cairns
    A combination of genetics, expression, genomic localization, and genomic nucleosome profiling demonstrates antagonism between two chromatin remodelers that reveal different mechanisms at different promoter architectures.
