Anti-KCNH5 antibodies are used in the immunodetection of the protein potassium voltage-gated channel subfamily H member 5. In humans, the canonical protein has a reported length of 988 amino acid residues and a mass of 111.9 kDa. Its subcellular localization is in the membrane. Up to 3 different isoforms have been reported for this protein. It is notably expressed in the brain, skeletal muscle, heart, placenta, lung and liver, and at low levels in the kidney. A member of the Potassium channel protein family, KCNH5 is known to be involved with potassium ion transport and the transport of ions. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include H-EAG2, Kv10.2, hEAG2, ether-a-go-go 2, and EAG2. KCNH5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of KCNH5 antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. In addition, Western Blot is also a common application.
