Potassium/Sodium Hyperpolarization-Activated Cyclic Nucleotide-Gated Channel 1

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** Potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 1 (890 aa, ~99 kDa) is encoded by the human HCN1 gene. This protein is involved in cyclic nucleotide-gated transport of potassium and sodium ions in neurons in the brain, heart and sensory organs.
