The dynamics of chromatin remodeling at promoters Mellor JMol Cell 2005[Jul]; 19 (2): 147-57The nucleosome, the structural unit of chromatin, is known to play a central role in regulating gene transcription from promoters. The last seven years have spawned a vast amount of data on the enzymes that remodel and modify nucleosomes and the rules governing how transcription factors interact with the epigenetic code on histones. Yet despite this effort, there has yet to emerge a unifying mechanism by which nucleosomes are remodeled during gene regulation. Recent advances have allowed nucleosome dynamics on promoters to be studied in real time, dramatically changing how we think about gene regulation on chromatin templates.|Animals[MESH]|Chromatin/metabolism/*physiology[MESH]|Histones/metabolism[MESH]|Humans[MESH]|Models, Biological[MESH]|Nucleosomes/*metabolism[MESH]|Promoter Regions, Genetic/genetics/*physiology[MESH] |
