    Effective dynamics of nucleosome configurations at the yeast PHO5 promoter

    Michael Roland Wolff et al.
    The integration of multi-nucleosome configuration data with histone turnover and new chromatin accessibility data by systematically investigated 'regulated on-off-slide' models reveals promoter state transitions regulated by just one assembly process.

    Acetylation of histone H3 at lysine 64 regulates nucleosome dynamics and facilitates transcription

    Vincenzo Di Cerbo et al.

    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.

    Enhancer regions show high histone H3.3 turnover that changes during differentiation

    Aimee M Deaton et al.
    Nucleosomes at enhancers are unusually dynamic and change histone turnover rates during differentiation.

    Dynamic regulation of transcription factors by nucleosome remodeling

    Ming Li et al.
    Single molecule DNA unzipping reveals a novel model for the regulation of transcription factors and nucleosome positioning via nucleosome remodeling in yeast.

    Archaeal chromatin ‘slinkies’ are inherently dynamic complexes with deflected DNA wrapping pathways

    Samuel Bowerman et al.
    Archaeal histones compact DNA into nucleosome-like particles of varying sizes that contort sporadically and reorient DNA wrapping.

    The RNF168 paralog RNF169 defines a new class of ubiquitylated histone reader involved in the response to DNA damage

    Julianne Kitevski-LeBlanc et al.
    A structural model of the dynamic complex comprising the histone reader RNF169 bound to an ubiquitylated nucleosome core particle reveals a three-pronged binding mechanism, which provides specificity for the recognition of DNA double-strand break sites.

    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.

    Nucleosome breathing and remodeling constrain CRISPR-Cas9 function

    R Stefan Isaac et al.
    The inhibitory influence of nucleosomes on CRISPR-Cas9 is mitigated by nucleosomal DNA breathing and chromatin remodeling.
