Figure 5From: All and only CpG containing sequences are enriched in promoters abundantly bound by RNA polymerase II in multiple tissues8-mer-association-with- RNAP vs. 8-mer enrichment in 356 liver specific promoters for abundant 8-mers. Highlighted 8-mers contain TATA sequences (STable 1 in Additional file 4) and the liver specific HNF4 binding sites (8-mers containing TGACCT). The CpG containing 8-mers are plotted in black.Back to article page
