Ctcf and cellular heterogeneity
DNA methylation can block CTCF binding in genome [34, 59,60,61]. The H19 imprinted control region (ICR) is an enhancer-blocking element required for imprinting of the H19 and Igf2 genes [62]. The conserved CTCF sites in HS1 and HS2 of the ICR are essential for the enhancer-blocking activity. The … See more CTCF gene encodes a transcriptional regulator protein with 11 highly conserved zinc finger (ZF) domains which exhibit almost identical amino acid sequences among vertebrates, and more divergent in N and C terminals … See more Although there is increasingly convincing evidence showing that CTCF critically contributes to the interaction between enhancers and promoters, depletion of CTCF protein in cells … See more The mammalian genomes are organized into megabase-sized local chromatin interaction domains, the topologically associating domains (TADs) defined from Hi-C interactions [9]. … See more Although CTCF binding is enriched in TAD boundaries and important for TAD structure, CTCF binding sites are widespread in the genome and actually the vast majority of … See more WebExpression of CTCF in K562 Cells Inhibits Cell Proliferation and Enhances Erythroid Differentiation-The re- sults of our transient transfection studies with ODN suggested that CTCF down-regulation ...
