Anti-HCN3 antibodies are used in the immunodetection of the protein hyperpolarization activated cyclic nucleotide gated potassium channel 3. In humans, the canonical protein has a reported length of 774 amino acid residues and a mass of 86 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in the brain. A member of the Potassium channel HCN protein family, HCN3 is known to be involved with potassium ion transport. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 3. HCN3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of HCN3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
