Gene: HCN1 (hyperpolarization activated cyclic nucleotide gated potassium channel 1) Homo sapiens
Symbol: HCN1
Name: hyperpolarization activated cyclic nucleotide gated potassium channel 1
Description: Exhibits cAMP binding activity; voltage-gated potassium channel activity; and voltage-gated sodium channel activity. Involved in several processes, including cellular response to cAMP; inorganic cation transmembrane transport; and protein homotetramerization. Localizes to HCN channel complex. Implicated in early infantile epileptic encephalopathy 24 and generalized epilepsy with febrile seizures plus 10. Biomarker of temporal lobe epilepsy.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: BCNG-1; BCNG1; brain cyclic nucleotide gated channel 1; brain cyclic nucleotide-gated channel 1; EIEE24; GEFSP10; HAC-2; hyperpolarization activated cyclic nucleotide-gated potassium channel 1; hyperpolarization-activated, cyclic nucleotide-gated potassium channel 1 (hcn1); potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 1
