Automated description from the Alliance of Genome Resources (Release 5.3.0)
Enables calmodulin binding activity; potassium channel activity; and voltage-gated ion channel activity. Acts upstream of or within establishment of localization in cell; membrane hyperpolarization; and potassium ion transmembrane transport. Located in cell surface; main axon; and plasma membrane. Part of 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).
