Both constitutively bound and exclusively post-RA RAR binding sites are coincident with ES cell regulatory events. Line-plot clustergram of ChIP-seq enrichment in 1-kbp windows centered on 1,924 post-RA RAR binding sites. Color shading denotes scaled ChIP-seq read depth (see Materials and methods).
