HCN1, Official Symbol HCN1provided by HGNC Official Full Name hyperpolarization activated cyclic nucleotide gated potassium channel 1provided by HGNC Primary source HGNC:HGNC:4845 See related Ensembl:ENSG00000164588 MIM:602780; AllianceGenome:HGNC:4845 Gene type protein coding RefSeq status REVIEWED Organism Homo sapiens Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo Also known as BCNG1; DEE24; HAC-2; BCNG-1; EIEE24; GEFSP10 Summary The membrane protein encoded by this gene is a hyperpolarization-activated cation channel that contributes to the native pacemaker currents in heart and neurons. The encoded protein can homodimerize or heterodimerize with other pore-forming subunits to form a potassium channel. This channel may act as a receptor for sour tastes.
