A number of ELISA Kits are available that target KCHAN, an alias of the protein, potassium voltage-gated channel subfamily A member 4. The human protein, encoded by the gene KCNA4, is a member of the Potassium channel family, A (Shaker) (TC 1.A.1.2) subfamily, Kv1.4/KCNA4 sub-subfamily. The protein's cellular localization is indicated to be membrane-associated. Additional synonyms or past names for this protein may include: HBK4, HK1, HPCN2, HUKII, KCNA4L, KCNA8, KV1.4, MCIDDS, PCN2. Homology is conserved in other species, such as Mouse, Rat, Zebrafish, Frog, Chicken.
