The role of ATP-dependent machines in regulating genome topology.

ABSTRACT: All cells must copy and express genes in accord with internal and external cues. The proper timing and response of such events relies on the active control of higher-order genomic organization. Cells use ATP-dependent molecular machines to alter the local and global topology of DNA so as to promote and counteract the persistent effects of transcription and replication. X-ray crystallography and electron microscopy, coupled with biochemical and single molecule methods are continuing to provide a wealth of mechanistic information on how DNA remodeling factors are employed to dynamically shape and organize the genome.
