Enriched TEs are often bound by additional TFs, besides ERα. The heat-maps show the fraction of enriched TEs in the datasets which carry particular computationally predicted TFBSs. A refers to the CM dataset while B refers to the E2T dataset. Yellow corresponds to low enrichment fractions, blue to high enrichment fractions. In the figure we also report the hierarchical clustering of both TEs and TFs.
