WebBPTF plays an important role in regulating nucleosome occupancy at nucleosome-free regions (NFRs) at sites occupied by the multivalent factors CTCF and cohesin via direct interaction with CTCF and the cohesin subunit SA2. In addition, BPTF also interacts with c-MYC and plays an essential role in its genomic distribution and biological activity. WebSep 16, 2024 · Other domains of CTCF do not show similar properties. Accordingly, endogenous CTCF forms small protein clusters and binds genomic regions with a high abundance of CTCF motifs but low densities of transcriptional activators, which is consistent with a spatial segregation model of CTCF insulation (Figure S5 A). Furthermore, the …
