Schematic diagram illustrating the chromatin patterns around enriched TFBSs.

<p>H2A.Z, H3K4me1, H3K4me2, H3K4me3, H3K9ac and H3K27ac were located mainly within the two nucleosomes proximal to the enriched sites, while the one local maxima for H3K79me2 were located within the forth nucleosome on one side of TFBSs. The mark signals were not smoothed. The red ellipses represent H2A.Z-containing nucleosomes; the gray ellipses represent typical nucleosomes; the triangles represent different histone modifications.
