Global Mapping of H3K4me1 and H3K4me3 Reveals the Chromatin State-Based Cell Type-Specific Gene Regulation in Human Treg Cells
Figure 2
Distribution and tag density of H3K4me3 enriched peaks. Panel A
, An illustration of the four regions that the human genome was divided into: proximal promoters, exons, introns, and intergenic sequences [39]. The number of islands detected for each sample is listed (Total), followed by the islands among genomic regions with the percentage they comprise listed in the parenthesis. Panel B, Tag density of H3K4me3 enriched peaks in Treg and aTconv cells. Tag density was plotted by splitting upstream (5Kb), downstream(5Kb) and gene body into 40 windows, respectively. Tag density = number of reads in specific region/(reads total number×specific region length).
