Anti-CACNG4 antibodies are used in the immunodetection of the protein calcium voltage-gated channel auxiliary subunit gamma 4. In humans, the canonical protein has a reported length of 327 amino acid residues and a mass of 36.6 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in the heart left ventricle. A member of the PMP-22/EMP/MP20 protein family, CACNG4 is reported to regulate the activity of L-type calcium channels that contain CACNA1C as pore-forming subunit. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include TARP gamma-4, calcium channel, voltage-dependent, gamma subunit 4, neuronal voltage-gated calcium channel gamma-4 subunit, and voltage-dependent calcium channel gamma-4 subunit. CACNG4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CACNG4 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.
