    Structure and dynamics of the chromatin remodeler ALC1 bound to a PARylated nucleosome

    Luka Bacic et al.
    Analysis of conformational heterogeneity in cryo-EM data by a recently developed deep learning method reveals the structure and dynamics of the oncogenic chromatin remodeler ALC1 bound to a poly-ADP-ribosylated nucleosome.

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

    Alisha Schlichter et al.
    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.

    High-resolution and high-accuracy topographic and transcriptional maps of the nucleosome barrier

    Zhijie Chen et al.
    Direct observation of RNA Polymerase II transcription through a single nucleosome at near basepair resolution suggests a mechanism for selective control of gene expression.

    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.

    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.

    A twist defect mechanism for ATP-dependent translocation of nucleosomal DNA

    Jessica Winger et al.
    Based on its nucleotide-bound state, the Chd1 chromatin remodeler can locally alter DNA twist on the nucleosome, which either pulls in or expels ~1 bp of DNA at the internal SHL2 binding site.

    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.

    The conformation of the histone H3 tail inhibits association of the BPTF PHD finger with the nucleosome

    Emma A Morrison et al.
    The BPTF PHD finger is inhibited from binding the methylated H3 tails in the context of the nucleosome due to their robust interaction with the nucleosomal DNA, which can be modulated by additional histone PTMs.

    H2A histone-fold and DNA elements in nucleosome activate SWR1-mediated H2A.Z replacement in budding yeast

    Anand Ranjan et al.
    Specific elements of the canonical nucleosome are recognized by the multi-component SWR1 chromatin remodeler for ATP-dependent replacement of H2A-H2B dimers with H2A.Z-H2B.

    Chromatin is an ancient innovation conserved between Archaea and Eukarya

    Ron Ammar et al.
    Similarities in the way that nucleosomes are organized into chromatin in archaea and eukaryotes suggest that chromatin might have been involved in gene regulation before its role in DNA packaging evolved.
