Automated description from the Alliance of Genome Resources (Release 3.2)
Exhibits cAMP binding activity; cation channel activity; and identical protein binding activity. Involved in several processes, including apical protein localization; cellular response to cAMP; and retinal cone cell development. Localizes to axon; dendrite; and integral component of plasma membrane. Is expressed in brain; heart; and heart ventricle. Used to study sick sinus syndrome. Human ortholog(s) of this gene implicated in early infantile epileptic encephalopathy 24 and generalized epilepsy with febrile seizures plus 10. Orthologous to human HCN1 (hyperpolarization activated cyclic nucleotide gated potassium channel 1).
