Figure 1From: Number of active transcription factor binding sites is essential for the Hes7 oscillatorSchematic representation of Hes7-dimer binding in the regulatory region of Hes7. Binding sites are indicated by three rectangles. E and N denote an E- or an N-box binding site, respectively. We assume that association and dissociation are in equilibrium. K denotes the respective equilibrium constants. 0 or 1 indicates whether the respective binding sites are occupied or not.Back to article page
