Automated description from the Alliance of Genome Resources
Exhibits intracellular cAMP-activated cation channel activity. Involved in cation transport; in utero embryonic development; and regulation of heart contraction. Localizes to the axon. Human ortholog(s) of this gene implicated in Brugada syndrome 8; Gilles de la Tourette syndrome; and sick sinus syndrome. Is expressed in eye; future brain; heart; septum transversum; and venous system. Orthologous to human HCN4 (hyperpolarization activated cyclic nucleotide gated potassium channel 4).
