Pioneer transcription factors bind closed chromatin regions, alter local accessibility and activate target genes. A study reveals that the SOX9 transcription factor drives cell fate switching by activating hair follicle cell enhancers, while simultaneously repressing epidermal enhancers via sequestration of epigenetic factors.
