GATA switch sites have higher H3K4me3 and Pol II signals than single-factor bound sites. (A) Tag density heatmaps as in Figure 5A for each of the 5451 GATA switch sites (top), the 4184 GATA1 selective binding sites (middle), and the 7840 GATA2 selective binding sites (bottom). (B-D) Box-and-whisker plots show the tag counts for genomic regions bound by GATA1 and/or GATA2, as in Figure 5E through G.
