HCN1 (Hyperpolarization Activated Cyclic Nucleotide Gated Potassium Channel 1) is a Protein Coding gene. Among its related pathways are Potassium Channels and Transmission across Chemical Synapses. The membrane protein encoded by HCN1 is a hyperpolarization-activated cation channel that contributes to the native pacemaker currents in heart and neurons. The encoded protein can homodimerize or heterodimerize with other pore-forming subunits to form a potassium channel. This channel may act as a receptor for sour tastes.
