Fig. 4From: Impact of vitamin D metabolism on clinical epigeneticsCooperativity between VDR and other nuclear receptors (NFRs) and linking to the basal transcriptional machinery. Accessory transcription factors (ATFs) may be localized more or less proximal or distal of VDR, with distances of up to several hundreds of base pairs, which can be overcome by loop domains of the transcriptional complexBack to article page
