Listed are ELISA Kits for the detection of RHK1, an alias name of potassium voltage-gated channel subfamily A member 4. The human protein, encoded by the gene KCNA4, is 653 amino acid residues long and has a mass of 73,257 daltons. It is a member of the Potassium channel family, A (Shaker) (TC 1.A.1.2) subfamily, Kv1.4/KCNA4 sub-subfamily. This protein is reported to have a membrane cellular localization, and is glycosylated. The gene is associated with Microcephaly, cataracts, impaired intellectual development, and dystonia with abnormal striatum. This target may also be known as: fetal skeletal muscle potassium channel, potassium channel 2, potassium channel voltage gated shaker related subfamily A member 4, shaker-related potassium channel Kv1.4, and type A potassium channel.
