Summary: Enables intracellularly cAMP-activated cation channel activity. Acts upstream of or within in utero embryonic development; monoatomic cation transport; and regulation of heart contraction. Located in axon. Is expressed in several structures, including eye; future brain; heart; septum transversum; and venous system. Human ortholog(s) of this gene implicated in Brugada syndrome 8; Gilles de la Tourette syndrome; idiopathic generalized epilepsy; and sick sinus syndrome. Orthologous to human HCN4 (hyperpolarization activated cyclic nucleotide gated potassium channel 4). [provided by Alliance of Genome Resources, Nov 2024]

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.
