Gene: HCN2 (hyperpolarization activated cyclic nucleotide gated potassium and sodium channel 2) Homo sapiens
Symbol: HCN2
Name: hyperpolarization activated cyclic nucleotide gated potassium and sodium channel 2
Description: The protein encoded by this gene is a hyperpolarization-activated cation channel involved in the generation of native pacemaker activity in the heart and in the brain. The encoded protein is activated by cAMP and can produce a fast, large current. Defects in this gene were noted as a possible cause of some forms of epilepsy. [provided by RefSeq, Jan 2017]
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: BCNG-2; BCNG2; brain cyclic nucleotide gated channel 2; brain cyclic nucleotide-gated channel 2; HAC-1; hyperpolarization activated cyclic nucleotide gated potassium channel 2; hyperpolarization activated cyclic nucleotide-gated potassium channel 2; potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 2
