These CCCTC-binding factor (zinc finger protein) ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. CCCTC-binding factor (zinc finger protein) is an alias of the human CTCF gene, which encodes the protein, CCCTC-binding factor. Notably, CCCTC-binding factor (zinc finger protein) is known to play a role in the regulation of cell proliferation and the regulation of transcription, among other functions. The CTCF protein is 727 amino acid residues in length and 82.8 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus of the cell. In terms of tissue specificity, it is ubiquitously expressed across many tissue types. This protein is known to be sumoylated. Other names for this target antigen include CFAP108, FAP108, and MRD21.
