CTCF and BORIS bind to the same genomic regions simultaneously. a The distribution of peak intensity for CTCF (AllCTCF) and BORIS (AllBORIS) bound regions in the K562 cell line. The peak intensity (tag density) is shown for CTCF peaks that coincide with BORIS peaks (CTCF&BORIS), for BORIS peaks that coincide with CTCF peaks (BORIS&CTCF), and for CTCF-only and BORIS-only bound regions. Data are shown in logarithmic scale; ***p
