The following Hyperpolarization Activated Cyclic Nucleotide Gated Potassium Channel 4 ELISA kits are useful research tools for the measurement of hyperpolarization activated cyclic nucleotide gated potassium channel 4 in biological samples. In humans this protein is encoded by the HCN4 gene. This protein has been described to function in the transport of ions and potassium ion transport. The canonical protein structure is reported to have an amino acid length of 1203 residues, a mass of 129 kDa, and is a member of the Potassium channel HCN protein family. Its subcellular location is known to be in the cell membrane. In addition, it is reported to be highly expressed in thalamus, testis and in heart, both in ventricle and atrium. In certain instances, it is also post-translationally glycosylated. The gene encoding this protein has been associated with the disease, Sick sinus syndrome. This protein may also be known as EIG18, SSS2, potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 4, hyperpolarization activated cyclic nucleotide-gated cation channel 4, and BRGDA8.
