Description

Exhibits voltage-gated potassium channel activity. Involved in several processes, including heart contraction; membrane repolarization during cardiac muscle cell action potential; and regulation of ventricular cardiac muscle cell membrane repolarization. Predicted to localize to integral component of plasma membrane. Is expressed in several structures, including cardiovascular system; digestive system; gill; immune system; and muscle. Used to study long QT syndrome and short QT syndrome. Orthologous to human KCNH6 (potassium voltage-gated channel subfamily H member 6).
