Potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 1 is a protein that in humans is encoded by the HCN1 gene.[1][2][3][4]

Function[edit]

Hyperpolarization-activated cation channels of the HCN gene family, such as HCN1, contribute to spontaneous rhythmic activity in both heart and brain.[4]

Tissue distribution[edit]

HCN1 channel expression is found in the sinoatrial node,[5][6] the neocortex, hippocampus, cerebellar cortex, dorsal root ganglion, trigeminal ganglion and brainstem.[7][8][9][10][11]

Interactions[edit]

HCN1 has been shown to interact with HCN2.[12][13]

Epilepsy[edit]

De novo mutations in HCN1 cause epilepsy .[14]
