Chromatin remodelers are molecular motors that act on nucleosomes: they move them along DNA or (dis-)assemble them. Despite the fact that they perform essential regulatory functions in cells-their deregulation can contribute to the development of cancers and lead to cell deathchromatin remodelers have only received meagre attention in the biophysics community so far. In this short text we attempt to present the key features of this interesting class of enzymes obtained with different experimental and theoretical methods, thereby providing a concise introduction for biophysicists to further stimulate interest in their properties.
