A Simple Grammar Defines Activating and Repressing cis-Regulatory Elements in Photoreceptors. Transcription factors often activate and repress different target genes in the same cell. How activation and repression are encoded by different arrangements of transcription factor binding sites in cis-regulatory elements is poorly understood. We investigated how sites for the transcription factor CRX encode both activation and repression in photoreceptors ...
