Project description:One bottleneck in understanding the principles of 3D chromatin structures is caused by the paucity of known regulators. Cohesin is essential for 3D chromatin organization, and its interacting partners are candidate regulators. Here, we performed proteomic profiling of the Cohesin in chromatin and identified transcription factors, RNA-binding proteins, and chromatin regulators associated with Cohesin. Acute protein degradation followed by time-series genomic binding quantitation and BAT Hi-C analysis were conducted, and the results showed that the transcription factor ZBTB21 contributes to Cohesin chromatin binding, 3D chromatin interactions and transcriptional repression. Strikingly, multiomic analyses revealed that the other four ZBTB factors interacted with Cohesin, and double degradation of ZBTB21 and ZBTB7B led to a further decrease in Cohesin chromatin occupancy. We propose that multiple ZBTB transcription factors orchestrate the chromatin binding of Cohesin to regulate chromatin interactions, and we provide a catalog of many additional proteins associated with Cohesin that warrant further investigation.
