Gene:
hyperpolarization activated cyclic nucleotide-gated potassium channel 4
Gene ID:
193429
Symbol:
HCN4
Species:
1000
Description:
Hyperpolarization-activated ion channel with very slow activation and inactivation exhibiting weak selectivity for potassium over sodium ions. May contribute to the native pacemaker currents in heart (If) and in neurons (Ih). Activated by cAMP. May mediate responses to sour stimuli.
