Enables identical protein binding activity; phosphatidylinositol-3,4,5-trisphosphate binding activity; and phosphatidylinositol-4,5-bisphosphate binding activity. Involved in several processes, including cellular response to interferon-beta; maternal behavior; and positive regulation of membrane hyperpolarization. Located in several cellular components, including basolateral plasma membrane; dendrite; and neuronal cell body. Used to study anxiety disorder; essential tremor; and mood disorder. Biomarker of childhood absence epilepsy; complex cortical dysplasia with other brain malformations; meningitis; status epilepticus; and temporal lobe epilepsy. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 24 and generalized epilepsy with febrile seizures plus 10. Orthologous to human HCN1 (hyperpolarization activated cyclic nucleotide gated potassium channel 1); INTERACTS WITH (+)-pilocarpine; 2,3,7,8-tetrachlorodibenzodioxine; 2,3,7,8-Tetrachlorodibenzofuran.
[Air Pollutants results in increased abundance of [Ozone co-treated with Soot]] which results in increased expression of HCN1 mRNA and [Air Pollutants results in increased abundance of Ozone] which results in increased expression of HCN1 mRNA
Enhanced expression of a specific hyperpolarization-activated cyclic nucleotide-gated cation channel (HCN) in surviving dentate gyrus granule cells of human and experimental epileptic hippocampus.
Inflammation-induced increase in hyperpolarization-activated, cyclic nucleotide-gated channel protein in trigeminal ganglion neurons and the effect of buprenorphine.
Activation of GABAB receptors ameliorates cognitive impairment via restoring the balance of HCN1/HCN2 surface expression in the hippocampal CA1 area in rats with chronic cerebral hypoperfusion.
Behavioral alterations associated with a down regulation of HCN1 mRNA in hippocampal cornus ammon 1 region and neocortex after chronic incomplete global cerebral ischemia in rats.
In the ventral cochlear nucleus Kv1.1 and subunits of HCN1 are colocalized at surfaces of neurons that have low-voltage-activated and hyperpolarization-activated conductances.
HCN1 and HCN2 proteins are expressed in cochlear hair cells: HCN1 can form a ternary complex with protocadherin 15 CD3 and F-actin-binding filamin A or can interact with HCN2.
