Anti-CACNB1 antibodies are used in the immunodetection of the protein calcium voltage-gated channel auxiliary subunit beta 1. In humans, the canonical protein has a reported length of 598 amino acid residues and a mass of 65.7 kDa. Its subcellular localization is in the cell membrane. Up to 3 different isoforms have been reported for this protein. It is notably expressed in the heart ventricle. A member of the Calcium channel beta subunit protein family, CACNB1 is a regulatory subunit of L-type calcium channels. Synonyms for this target antigen include CACNLB1, CCHLB1, voltage-dependent L-type calcium channel subunit beta-1, calcium channel voltage-dependent subunit beta 1, and CAB1. CACNB1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CACNB1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
