    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.

    CTCF confers local nucleosome resiliency after DNA replication and during mitosis

    Nick Owens et al.
    In contrast to other transcription factors, CTCF and Esrrb rapidly regain binding after replication and remain bound to their targets during mitosis, preserving local nucleosome organization throughout the cell cycle.

    Independent manipulation of histone H3 modifications in individual nucleosomes reveals the contributions of sister histones to transcription

    Zhen Zhou et al.
    A yeast genetic model for studying the function of sister histones in chromatin dynamics.

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

    Vincenzo Di Cerbo et al.
    The acetylation of histones at specific sites close to DNA can regulate transcription.

    Promoter nucleosome dynamics regulated by signalling through the CTD code

    Philippe Materne et al.
    Phosphorylation of the C-terminal domain (CTD) of RNA Polymerase II controls nucleosomes dynamics at specific promoters to regulate transcription.

    VivosX, a disulfide crosslinking method to capture site-specific, protein-protein interactions in yeast and human cells

    Chitra Mohan et al.
    An in vivo disulfide crosslinking assay shows preferential disassembly of nucleosomes with two H2A.Z histones by transcription machinery in yeast and conjugation to one or two ubiquitin moieties in human cells.

    Constitutive turnover of histone H2A.Z at yeast promoters requires the preinitiation complex

    Michael Tramantano et al.
    The transcription machinery is required for the disassembly of the promoter-proximal H2A.Z nucleosome, contributing to the constitutive histone turnover at yeast promoters.
