  5. Both LDB1 (show LDB1 Proteins) and CTCF are required for enhancer-Car2 (show CA2 Proteins) looping, and the domain of LDB1 (show LDB1 Proteins) contacted by CTCF is necessary to rescue Car2 (show CA2 Proteins) transcription in LDB1 (show LDB1 Proteins)-deficient cells.

  6. CTCF physically associates with Wdr5 (show WDR5 Proteins) and further transcriptionally controls its expression by directly targeting the Wdr5 (show WDR5 Proteins) gene promoter.

  7. This study confirms that haploinsufficiency of CTCF causes distinct clinical features, and that a microdeletion encompassing CTCF could cause a recognisable CTCF deletion syndrome. Perturbed DNA methylation (show HELLS Proteins) at CTCF binding sites, not at imprinted loci, may underlie the pathomechanism of the syndrome.

  8. structural studies show that the sequence-specific interactions between zinc fingers and CTCF-binding sites determine the directionality and conservation of CTCF recognition.

CTCF Protein Profile

Protein Summary

This gene is a member of the BORIS + CTCF gene family and encodes a transcriptional regulator protein with 11 highly conserved zinc finger (ZF) domains. This nuclear protein is able to use different combinations of the ZF domains to bind different DNA target sequences and proteins. Depending upon the context of the site, the protein can bind a histone acetyltransferase (HAT)-containing complex and function as a transcriptional activator or bind a histone deacetylase (HDAC)-containing complex and function as a transcriptional repressor. If the protein is bound to a transcriptional insulator element, it can block communication between enhancers and upstream promoters, thereby regulating imprinted expression. Mutations in this gene have been associated with invasive breast cancers, prostate cancers, and Wilms' tumors. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
