Distribution of CCAAT boxes in c-Fos-bound proximal regions.

<p>Shown are the numbers of ChIP-seq genomic intervals found in three cell lines (HeLa S3, K562, GM12878) that interact either with c-Fos (blue) or NF-YB (yellow), or with both of them (green). Left: Venn diagram displaying the distribution of proximal intervals among the three classes. Center: Histograms showing the numbers of intervals having no CCAAT box motif (0), one CCAAT box (1), two CCAAT boxes as inverted or everted repeat (1,1), or two or more CCAAT boxes as direct repeat (> = 2) related to the three data sets. The exact frequencies are given in each column. The histograms on the right show the distance distribution of the direct repeats for each class. The dashed lines highlight the distances 24 bp, 31 bp, 41 bp, and 51 bp.
