Many transcription factors bind to regulatory DNA elements that are distant from gene promoters. These distal binding sites are thought to regulate transcription through long-range chromatin interactions, but, until now, the impact of chromatin interactions on transcription regulation has not been investigated in a genome-wide manner. A new strategy — chromatin interaction analysis by paired-end tag sequencing — is now described for the de novo detection of global chromatin interactions.
