Protein name |
Potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 3 |
Comment |
FUNCTION:Putative hyperpolarization-activated ion channel exhibiting weak selectivity for potassium over sodium ions (By similarity).||SUBUNIT:The potassium channel is probably composed of a homo- or heterotetrameric complex of pore-forming subunits.||SUBCELLULAR LOCATION:Membrane; Multi-pass membrane protein.||DOMAIN:The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.||SIMILARITY:Belongs to the potassium channel HCN family.||SIMILARITY:Contains 1 cyclic nucleotide-binding domain.||SEQUENCE CAUTION:Sequence=AAH28024.2; Type=Erroneous initiation; |
