Summaries for HCN1 Gene

Entrez Gene Summary for HCN1 Gene

  • 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. [provided by RefSeq, Oct 2011]

GeneCards Summary for HCN1 Gene

HCN1 (Hyperpolarization Activated Cyclic Nucleotide Gated Potassium Channel 1) is a Protein Coding gene. Diseases associated with HCN1 include epileptic encephalopathy, early infantile, 24 and undetermined early-onset epileptic encephalopathy. Among its related pathways are Transmission across Chemical Synapses and Potassium Channels. GO annotations related to this gene include identical protein binding and voltage-gated potassium channel activity. An important paralog of this gene is KCNH1.

UniProtKB/Swiss-Prot for HCN1 Gene

  • 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.

Function for HCN1 Gene

Molecular function for HCN1 Gene

GENATLAS Biochemistry:
hyperpolarization-activated and cyclic nucleotide gated potassium channel 1,containing a CCG repeat in 5utr,related to Eag and H-erg,expressed in brain,potentially modulating excitability in the brain and responding to regulation by cyclic nucleotides,playing a critical role in shaping the autonomous activity of single neurons and the periodicity of network oscillations
UniProtKB/Swiss-Prot EnzymeRegulation:
Activated by cAMP, and at 10-100 times higher concentrations, also by cGMP. cAMP binding promotes tetramerization and formation of an active channel. Compared to other family members, cAMP has less stimulatory effect on HCN1 because part of the molecules already contain bound cAMP and form homotetramers when cAMP levels are low. Inhibited by Cs(1+), zatebradine, capsazepine and ZD7288.
UniProtKB/Swiss-Prot 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.
