Genome-wide mapping of RNA Pol II binding site (GM12878)

ABSTRACT: We report the results of chromatin immunoprecipitation following by high-thoughput sequencing (ChIP-Seq) using the GA II platform from Illumina for the human RNA Polymerase II in GM12878 cells. We have also generated a sequenced input DNA datasets for GM12878 cells. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf Map binding sites of RNA Polymerase II in the genome of GM12878 cells. The GM12878 input data has been deposited in GEO as GSM487430.

Transcription of the eukaryotic genomes is carried out by three distinct RNA polymerases I, II, and III, whereby each polymerase is thought to independently transcribe a distinct set of genes. To investigate a possible relationship of RNA polymerases II and III, we mapped their in vivo binding sites throughout the human genome by using ChIP-Seq in two different cell lines, GM12878 and K562 cells. Pol III was found to bind near many known genes as well as several previously unidentified target ge ...[more]

Project description:The human body contains thousands of unique cell types, each with specialized functions. Cell identity is governed in large part by gene transcription programs, which are determined by regulatory elements encoded in DNA. To identify regulatory elements active in seven cell lines representative of diverse human cell types, we used DNase-seq and FAIRE-seq to map M-CM-"M-BM-^@M-BM-^\open chromatinM-CM-"M-BM-^@M-BM-^]. Over 870,000 DNaseI or FAIRE sites, which correspond largely to nucleosome depleted regions (NDRs), were identified across the seven cell lines, covering nearly 9% of the genome. The combination of DNaseI and FAIRE is more effective than either assay alone in identifying likely regulatory elements, as judged by coincidence with transcription factor binding locations determined in the same cells. Open chromatin common to all seven cell types tended to be at or near transcription start sites and encompassed more CTCF binding sites, while open chromatin sites found in only one cell type were typically located away from transcription start sites, and contained DNA motifs recognized by regulators of cell-type identity. As one example of its ability to identify functional DNA, we show that open chromatin regions bound by CTCF are potent insulators. We identified clusters of open regulatory elements (COREs) that were physically near each other and whose appearance was coordinated among one or more cell types. Gene expression and RNA Pol II binding data support the hypothesis that COREs control gene activity required for the maintenance of cell-type identity. This publicly available atlas of regulatory elements may prove valuable in identifying non-coding DNA sequence variants that are causally linked to human disease.

For each cell line, two or three replicates were independently grown and split into three, one for each of the three experimental methods. Control ChIP experiments were performed on five of the cell lines with NHEK and H1-ES being excluded due to lack of material.
