Proteins/UNIPROT:O60741
Hyperpolarization-activated ion channel that are permeable to sodium and potassium ions. Displays lower selectivity for K(+) over Na(+) ions. Contributes to the native pacemaker currents in heart (If) and in the generation of the I(h) current which controls neuron excitability. Participates in cerebellar mechanisms of motor learning (By similarity). May mediate responses to sour stimuli (By similarity)..
