Summary: Enables cAMP binding activity; identical protein binding activity; and monoatomic cation channel activity. Involved in cellular response to cAMP; potassium ion transmembrane transport; and regulation of postsynaptic membrane potential. Acts upstream of or within several processes, including apical protein localization; general adaptation syndrome, behavioral process; and neuronal action potential. Located in axon; dendrite; and plasma membrane. Is active in glutamatergic synapse; postsynaptic membrane; and presynaptic active zone membrane. Is expressed in brain and heart. Used to study sick sinus syndrome. 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). [provided by Alliance of Genome Resources, Dec 2024]

Title: Cation leak underlies neuronal excitability in an HCN1 developmental and epileptic encephalopathy.
The ionic mechanism driving increased excitability involves alterations of the expression levels of HCN and KCNQ channel genes leading to a complex dynamic of H-current and M-current activation. Moreover, there is a negative correlation between the disease onset and disease progression, which correlates with a decrease in the expression level of HCN and KCNQ channels.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
