Figure 6From: Characteristic bimodal profiles of RNA polymerase II at thousands of active mammalian promotersPolII and H3K4me3 occupancy at TSSs correlate with CpG number, TATA score and mRNA expression. (a–f) Genomic profiles of ChIP-seq around TSSs for PolII (a, c, e) and H3K4me3 (b, d, f). Expression thresholds on microarray data are 6.0 and 8.0 as in Figure 1. (a, b) CpG-poor promoters have less than 50 CpG counts in TSS ± 1 kb (3,873 genes). (c, d) CpG-rich promoters have more than 50 CpG counts (2,520 genes). (f) High TATA score promoters have the top 2% of TATA scores (98 genes). (g, h) Microarray signal as a function of PolII ChIP-seq signals (g) and H3K4me3 ChIP-seq signals (h) within 1 kb of a TSS stratified by the CpG content of promoter sequences (see Materials and methods). A cross indicates that the point represents less than 1% of all TSSs. a.u., arbitrary units.Back to article page
