Transcriptional state plays a role in genome organization, however factors that link these processes are not well known. Here, the authors show Drosophila transcription factor Motif 1-binding protein (M1BP) interacts with the insulator protein CP190 to promote insulator function and activate Motif 1-dependent transcription at topologically associating domain (TAD) borders.
