Automated description from the Alliance of Genome Resources (Release 3.1.1)
Exhibits calmodulin binding activity; potassium channel activity; and voltage-gated ion channel activity. Involved in membrane hyperpolarization and potassium ion transmembrane transport. Localizes to cell surface; main axon; and voltage-gated potassium channel complex. Is expressed in several structures, including central nervous system; midgut; retina; and rib. Used to study benign neonatal seizures. Human ortholog(s) of this gene implicated in autistic disorder and benign neonatal seizures. Orthologous to human KCNQ3 (potassium voltage-gated channel subfamily Q member 3).
