Ten-eleven Translocation (TET) enzymes are methylcytosine dioxygenases that are involved in multiple cellular processes, including cellular differentiation and forced cell fate conversions. However, deciphering the molecular mechanisms underlying epigenetic control exerted by these proteins has been hampered by technical limitations, which prevent the identification of essential partners that work in concert with these enzymes to modulate gene expression. In this chapter, we provide a comprehensive description of cutting-edge methods designed to assess physical interactions between sequence-specific transcription factors and the TET2 enzyme.
