| Abstract |
Genetic information is organized in a complex structure composed of DNA and proteins together designated chromatin. Chromatin plays a dynamic role in transcriptional processes in that alteration of the interaction between its components results in the deregulation of cellular transcriptional program. Modification of epigenetic marks, variation in the precise positioning of nucleosomes, and consequent mobilization of nucleosomes regulate the access of various transcriptional factors to its underlying DNA template. Nucleosome-depleted regions, also designated open chromatin domains, are associated with active DNA regulatory elements, including promoters, enhancers, silencers, and insulators. Here, we describe the protocol of a rapid and simple technique entitled FAIRE (formaldehyde-assisted isolation of regulatory elements). Combined with high-throughput sequencing (FAIRE-seq), this procedure allows isolation of nucleosome-free regions and their mapping along the genome, thereby providing a global view of cell-specific regulatory elements. |
