    Summary
    Enables voltage-gated monoatomic cation channel activity. Involved in several processes, including cardiac muscle contraction; potassium ion transport; and regulation of heart rate. Located in membrane. Is expressed in several structures, including adult brain cell body rind; adult head; egg chamber; female germline cell; and lamina. Used to study heart conduction disease and long QT syndrome. Human ortholog(s) of this gene implicated in auditory system disease (multiple); autistic disorder; autosomal dominant intellectual developmental disorder 46; and electroclinical syndrome (multiple). Orthologous to several human genes including KCNQ4 (potassium voltage-gated channel subfamily Q member 4). [provided by Alliance of Genome Resources, Dec 2024]
