Anti-CACNB4 antibodies are used in the immunodetection of the protein calcium voltage-gated channel auxiliary subunit beta 4. In humans, the canonical protein has a reported length of 520 amino acid residues and a mass of 58.2 kDa. Up to 4 different isoforms have been reported for this protein. It is reported to be highly expressed in the cerebellum and kidney. A member of the Calcium channel beta subunit protein family, CACNB4 is known to be involved with chemical synaptic transmission and the regulation of cell proliferation. The CACNB4 gene has been associated with the disease, Epilepsy. Synonyms for this target antigen include CACNLB4, EA5, EIG9, EJM, EJM4, EJM6, voltage-dependent L-type calcium channel subunit beta-4, and CAB4. CACNB4 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of CACNB4 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
