| Outline of Final Research Achievements |
The cells in our body select distinct subsets of genes in the genome, thereby generating a variety of unique cell types and responding appropriately to changes in the environment. Since the selection is done by the transcription factors and nucleosomes bound to the genomic DNA, it is critical to comprehensively reveal their binding sites for an in-depth understanding of genome functions. We have developed a novel method termed DMS-seq using dimethylsulfate, a cell-permeable DNA-modification reagent, and next-generation sequencer. DMS-seq has, for the first time, enabled comprehensive identification of transcription factor-binding sites and the center positions of nucleosomes without nuclear isolation and genetic manipulations. We expect that DMS-seq provides a unique method to accelerate our understanding of genomic regulation.
