Regulation of ISWI involves inhibitory modules antagonized by nucleosomal epitopes

CR Clapier, BR Cairns - Nature, 2012 - nature.com
Chromatin-remodelling complexes (CRCs) mobilize nucleosomes to mediate the access of
DNA-binding factors to their sites in vivo. These CRCs contain a catalytic subunit that bears …

Ruler elements in chromatin remodelers set nucleosome array spacing and phasing

E Oberbeckmann, V Niebauer, S Watanabe… - Nature …, 2021 - nature.com
