WebWe noticed that multiple CTCF-binding sites are present in the BCL11B enhancer region that are complementary (convergent) to those found in the transcriptional regulatory regions of BCL11B and TLX3 (Figure 4 A). Seventeen out of 31 patients and both cell lines contained CTCF deletions or mutations, whereas 14 patients were CTCF wild type. WebCTCF is an architectural protein with a critical role in connecting higher-order chromatin folding in pluripotent stem cells. Recent reports have suggested that CTCF binding is more dynamic during development than previously appreciated.

WebMar 11, 2024 · While constitutive CCCTC-binding factor (CTCF)–binding sites are needed to maintain relatively invariant chromatin structures, such as topologically associating domains, the precise roles of CTCF to control cell-type–specific transcriptional regulation remain poorly explored.

WebJun 24, 2024 · Occupancy with CTCF is tissue-specific and it is influenced by DNAm [57, 58]. In turn, CTCF was also capable to change DNAm status, for instance, by reducing the DNAm level at the vicinity of its binding positions . Thus, the relevance of CTCF-binding for age-associated DNAm changes needs to be further explored.
