Anti-CACNA1I antibodies are used in the immunodetection of the protein calcium voltage-gated channel subunit alpha1 I. In humans, the canonical protein has a reported length of 2223 amino acid residues and a mass of 245.1 kDa. Its subcellular localization is in the membrane. Up to 4 different isoforms have been reported for this protein. It is reported to have brain specific expression. A member of the Calcium channel alpha-1 subunit (TC 1.A.1.11) protein family, CACNA1I is known to be involved with the transport of ions and signal transduction pathways. Synonyms for this target antigen include NEDSIS, ca(v)3.3, voltage-dependent T-type calcium channel subunit alpha-1I, calcium channel, voltage-dependent, T type, alpha 1I subunit, and Cav3.3. CACNA1I gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of CACNA1I antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
