WebJul 21, 2024 · To test whether CTCF and MCM function together to establish the strength of CTCF-mediated loops, they exploited a CTCF knockdown in MCM-deficient zygotes. Both loops and TADs were lost with or without MCM, indicating that MCM has no function in establishing loop boundaries; thus, only CTCF sites act as loop anchors ( Figure 1 D). WebChIP-seq on CTCF-aberrant patient cells with a distal BCL11B enhancer confirmed binding of CTCF and cohesin to the remaining intervening CTCF motifs, despite the lower CTCF levels in these patients. 4C-seq further showed that in these patients, the TLX3 promoter forms secondary loops with these intervening CTCF sites.
