Function

edit

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

edit

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

edit

Interactions

edit

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

Epilepsy

edit

De novo mutations in HCN1 cause epilepsy.[22]
