The Venn diagrams showing the pair-wise overlap between CTCF and Rad21, Smc3, and Znf143 when both are constitutive or non-constitutive. Counts provide for each region in the Venn diagrams. Figure S2. The Venn diagrams showing the trio-wise overlap between CTCF and Rad21 and Smc3, Rad21 and Znf143, and Znf143 and Smc3 when both are constitutive or non-constitutive. Figure S3. Box plots of the fraction of overlap within each cell line between classes of CTCF sites and various factors/features. Figure S4. Density of epigenetic marks cCTCF/cCohesin loci (top panels, black) and the cCTCF-Cohesin loci (bottom panels, red) in Gm12878, Helas3, Hepg2, and K562 cell lines.
