Transcription factors only bind a minority of their motifs in large mammalian genomes. One potential explanation is that many motifs are not accessible for binding due to the action of chromatin and DNA methylation. We are using mammalian stem cell models to understand this important interplay between gene regulation, chromatin structure and DNA methylation. We study the dynamics of the epigenome and test regulatory models in cellular models by genetic perturbation and genome editing approaches.

I will discuss our recent efforts in understanding how the sensitivity to DNA methylation can limit transcription factor binding in the context of the cell and how TFs rely on specific chromatin remodelers for access to their binding sites.
