Protein: Potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 1 (Brain cyclic nucleotide-gated channel 1) (BCNG-1) (Hyperpolarization-activated cation channel 2) (HAC-2) (O88704)
Organism: Mus musculus (Mouse)
Function: Hyperpolarization-activated ion channel exhibiting weak selectivity for potassium over sodium ions. Contributes to the native pacemaker currents in heart (If) and in neurons (Ih). May mediate responses to sour stimuli.
Subcellular location: Cell membrane {ECO:0000269|PubMed:11459060, ECO:0000269|PubMed:22006928, ECO:0000269|PubMed:9630217}; Multi-pass membrane protein {ECO:0000269|PubMed:22006928}.
