Anti-KCTD8 antibodies are used in the immunodetection of the protein potassium channel tetramerization domain containing 8. In humans, the canonical protein has a reported length of 473 amino acid residues and a mass of 52.4 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in the cerebellum and cerebral cortex. KCTD8 is reported to be an auxiliary subunit of GABA-B receptors that determine the pharmacology and kinetics of the receptor response. Synonyms for this target antigen include BTB/POZ domain-containing protein KCTD8 and potassium channel tetramerisation domain containing 8. KCTD8 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Immunohistochemistry is the most common application for the Kctd8 antibodies listed below. Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
