Figure 3

Clustering of enhancer regions according to bound TFs. For the 13 enhancer classes (rows) the average normalized peak score for the 6 principal TFs (columns) is shown. Colors represent the average rates of binding of each TF in each class of enhancers, with red, white, and blue colors indicating high, intermediate, and low rates of binding, respectively. Columns on the right of the heatmap show for each class the index, the number of regions in the class in unstimulated cells, and the corresponding percentage of the total set of enhancers.
