HCN3 (Hyperpolarization Activated Cyclic Nucleotide Gated Potassium Channel 3) is a Protein Coding gene. Among its related pathways are Potassium Channels and Transmission across Chemical Synapses. HCN3 encodes a multi-pass membrane protein that functions as a voltage gated cation channel. The encoded protein is a member of a family of closely related cyclic adenosine monophosphate-binding channel proteins. Alternative splicing results in multiple transcript variants.
