"WebThis raises the question of whether the properties of CTCF/MAZ double binding sites differ from those of CTCF-only sites. Most CTCF sites are associated with cohesin (8–12). CTCF is known to help form chromatin loop domains generated by the action of cohesin, which brings together pairs of distant sites on chromatin. " - Ctcf-only
