HCN4

Gene
HCN4
Protein
Potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 4
Organism
Homo sapiens
Length
1203 amino acids
Function
Hyperpolarization-activated ion channel with very slow activation and inactivation exhibiting weak selectivity for potassium over sodium ions. Contributes to the native pacemaker currents in heart (If) that regulate the rhythm of heart beat. May contribute to the native pacemaker currents in neurons (Ih). May mediate responses to sour stimuli.
Similarity
Belongs to the potassium channel HCN family.
