Cohesin binding can be independent of CTCF. (A) Cohesin (STAG1 and RAD21) enrichment at cohesin-CTCF sites is reduced upon CTCF removal by RNAi knockdown (CTCF k.d.). (B) Cohesin enrichment at ER-CNCs is largely unaffected by CTCF knockdown. (C) Cohesin binding increases upon estrogen treatment at sites not shared with CTCF (Kolmogorov-Smirnov, P-value < 10−9 [STAG1]; P-value < 10−15 [RAD21]).
