Anti-KCTD1 antibodies are used in the immunodetection of the protein potassium channel tetramerization domain containing 1. In humans, the canonical protein has a reported length of 257 amino acid residues and a mass of 29.4 kDa. Its subcellular localization is in the nucleus. It is reported to be expressed in mammary gland, kidney, brain and ovary. KCTD1 is believed to repress the transcriptional activity of AP-2 family members, including TFAP2A, TFAP2B and TFAP2C to various extent. Post-translational modifications have been described, including sumoylation. The KCTD1 gene has been associated with the disease, Scalp-ear-nipple syndrome. Synonyms for this target antigen include BTB/POZ domain-containing protein KCTD1. KCTD1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the Kctd1 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
