Background
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.

Immunofluorescence analysis of U2OS cells using CTCF antibody (144-01133) at dilution of 1:100. Blue: DAPI for nuclear staining.
Immunoprecipitation analysis of 200ug extracts of HeLa cells, using 3 ug CTCF antibody (144-01133). Western blot was performed from the immunoprecipitate using CTCF antibody (144-01133) at a dilition of 1:1000.
Chromatin immunoprecipitation analysis extracts of HCT116 cells, using CTCF antibody (144-01133) and rabbit IgG. The amount of immunoprecipitated DNA was checked by quantitative PCR. Histogram was constructed by the ratios of the immunoprecipitated DNA to the input.
