Potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 1

UniProtKB accession:  O88704

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Hyperpolarization-activated ion channel that are permeable to sodium and potassium ions (PubMed:12034718, PubMed:22006928, PubMed:9630217). Exhibits weak selectivity for potassium over sodium ions (PubMed:11459060). Contributes to the native pacemaker currents in heart (If) and in neurons (Ih) (PubMed:11459060). Participates in cerebellar mechanisms of motor learning (PubMed:14651847). May mediate responses to sour stimuli (PubMed:11675786).
