Potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 1 is a protein that in humans is encoded by the HCN1 gene.^[5]^[6]^[7]^[8]

Function

Hyperpolarization-activated cation channels of the HCN gene family, such as HCN1, contribute to spontaneous rhythmic activity in both heart and brain.^[8]

Tissue distribution

HCN1 channel expression is found in the sinoatrial node,^[9]^[10] the neocortex, hippocampus, cerebellar cortex, dorsal root ganglion, trigeminal ganglion and brainstem.^[11]^[12]^[13]^[14]^[15]

Ligands

Ketamine is an inhibitor of HCN1 in addition to its other targets.^[16]^[17]

Propofol also inhibits HCN1.^[18]

Isoflurane and Sevoflurane inhibit HCN1.^[19]

Interactions

HCN1 has been shown to interact with HCN2.^[20]^[21]

Epilepsy

De novo mutations in HCN1 cause epilepsy.^[22]
