Figure 2.

Sharp increases in H4K20me1, H2BK5me1, and H3K79me1 modification levels in the bodies of CpG promoter genes. (a-c) Average profiles of H4K20me1 (a), H2BK5me1 (b) and H3K79me1 (c) for expression-matched groups of CpG and non-CpG promoter genes (color-coded as in Figure 1a). Arrows indicate modification peaks unique to CpG promoter genes. TSS, transcription start site.
