    FACT and Ubp10 collaborate to modulate H2B deubiquitination and nucleosome dynamics

    Melesse Nune et al.
    The histone chaperone FACT and the deubiquitinating enzyme Ubp10 act in concert to remove ubiquitin from histone H2B in nucleosomes, and likely coordinate nucleosome assembly during DNA replication and transcription.

    Nucleosomes impede Cas9 access to DNA in vivo and in vitro

    Max A Horlbeck et al.
    Nucleosomes provide a direct and profound block to the activity of the CRISPR effector protein Cas9, suggesting future sophisticated design rules for CRISPR targeting.

    Human cytomegalovirus IE1 protein alters the higher-order chromatin structure by targeting the acidic patch of the nucleosome

    Qianglin Fang et al.
    Distinct binding of viral proteins to the same region on the nucleosome surface can result in contrasting changes to higher-order chromatin structure in the host cell.

    Structure of the chromatin remodelling enzyme Chd1 bound to a ubiquitinylated nucleosome

    Ramasubramanian Sundaramoorthy et al.
    The unwrapping two turns of DNA on Chd1-bound nucleosomes cause the histone H3 tail and ubiquitin to be re-positioned.

    Ion counting demonstrates a high electrostatic field generated by the nucleosome

    Magdalena Gebala et al.
    First experimental studies on the ion atmosphere around a nucleosome provide a quantitative analysis of the molecule's electrostatic properties.

    Heterochromatin assembly by interrupted Sir3 bridges across neighboring nucleosomes

    Reza Behrouzi et al.
    Cooperative association of a histone-binding complex with pairs of appropriately modified nucleosomes, which form fundamental units of binding, mediates selective heterochromatin assembly and spreading.

    Arabidopsis FORGETTER1 mediates stress-induced chromatin memory through nucleosome remodeling

    Krzysztof Brzezinka et al.
    Environmentally-mediated gene induction is extended beyond the duration of an external cue by sustaining a nucleosome-depleted chromatin structure.

    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.

    A computational approach to map nucleosome positions and alternative chromatin states with base pair resolution

    Xu Zhou et al.
    Computational analysis of MNase-seq data reveals that alternatively positioned nucleosomes are prevalent in both yeast and human cells and create significant heterogeneity within cell populations.
