Enrichment profiles of the top 10 tissues for 4 transcription factors. POU5F1, FOXP3, PHF7, and ATF5 are known for their role in embryonic stem cells (ES cells), T regulatory cells, testes, and liver, respectively. Bars are color-coded for the enrichment score relative to the distribution of highest and lowest score per gene. The values in the color scheme on top represent the percentiles of these distributions.
