Anti-KCNAB1 antibodies are used in the immunodetection of the protein potassium voltage-gated channel subfamily A regulatory beta subunit 1. In humans, the canonical protein has a reported length of 419 amino acid residues and a mass of 46.6 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably expressed in many tissues, such as the bronchus, soft tissue, and appendix. A member of the Shaker potassium channel beta subunit protein family, KCNAB1 is known to be involved with the transport of ions. Synonyms for this target antigen include KCNA1B, KV-BETA-1, Kvb1.3, hKvBeta3, hKvb3, and AKR6A3. KCNAB1 gene orthologs have been reported in the mouse, rat, frog, zebrafish, chimpanzee and chicken species. Some KCNAB1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
