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. Used to study long QT syndrome and short QT syndrome. Is expressed in several structures, including cardiovascular system; digestive system; gill; immune system; and muscle. Orthologous to human KCNH6 (potassium voltage-gated channel subfamily H member 6).
