title: Chromatin remodelling: the industrial revolution of DNA around histones.
abstract: Chromatin remodellers are specialized multi-protein machines that enable access to nucleosomal DNA by altering the structure, composition and positioning of nucleosomes. All remodellers have a catalytic ATPase subunit that is similar to known DNA-translocating motor proteins, suggesting DNA translocation as a unifying aspect of their mechanism. Here, we explore the diversity and specialization of chromatin remodellers, discuss how nucleosome modifications regulate remodeller activity and consider a model for the exposure of nucleosomal DNA that involves the use of directional DNA translocation to pump 'DNA waves' around the nucleosome.
