Figure 3

Nucleosome positioning around TSS (revisited). A Nucleosome binding patterns around the top 1.5 k expressed TSSs by exon-expression. No alternative TSSs were allowed in the plotted regions. In the top panel, the individual signals (+/- 1 kb) are clustered. The grey scale indicator to the left correspond to length of first exons, light to dark (shorter to longer). The mid-panel shows the resulting footprint for all signals and the bottom panel footprints for the individual clusters. Colors correspond to the rightmost color guide in the top panel. The black line is the combined signal. B Nucleosome binding patterns centred between bidirectional genes found at most 1 kb apart. Panels as in A. Clusters with less than 5 members (1 found) are excluded from the bottom-panel. The grey scale indicator to the left correspond to distance between bidirectional TSS's, light to dark (closer to distant).
