Potassium/Sodium Hyperpolarization-Activated Cyclic Nucleotide-Gated Channel 4

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

**Definition:** Potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 4 (1203 aa, ~129 kDa) is encoded by the human HCN4 gene. This protein plays a role in the transport of potassium and sodium ions and the regulation of native pacemaker currents in neurons and the heart.

**Synonyms:** - HCN4 - Hyperpolarization Activated Cyclic Nucleotide Gated Potassium Channel 4 - Hyperpolarization Activated Cyclic Nucleotide-Gated Cation Channel 4 - Hyperpolarization Activated Cyclic Nucleotide-Gated Potassium Channel 4
