There are a number of ELISA Kits available for the measurement of hyperpolarization-activated cyclic nucleotide-gated potassium channel 1, another term for the human protein, hyperpolarization activated cyclic nucleotide gated potassium channel 1. Other synonyms may include: potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 1, brain cyclic nucleotide-gated channel 1, BCNG-1, BCNG1, GEFSP10, and HAC-2. It is encoded by the HCN1 gene to yield a protein 890 amino acids in length and 98.8 kDa in size. The protein is categorized into the Potassium channel HCN family. Versions of hyperpolarization-activated cyclic nucleotide-gated potassium channel 1 are present in other organisms, including: Mouse, Rat, Frog.
