Automated description from the Alliance of Genome Resources
Exhibits inward rectifier potassium channel activity. Involved in potassium ion transmembrane transport; regulation of heart rate by cardiac conduction; and regulation of ventricular cardiac muscle cell membrane repolarization. Localizes to the cytoplasm; nuclear envelope; and plasma membrane. Used to study short QT syndrome. Human ortholog(s) of this gene implicated in long QT syndrome; long QT syndrome 2; and short QT syndrome. Is expressed in several structures, including brain; early conceptus; gonad; heart; and retina. Orthologous to human KCNH2 (potassium voltage-gated channel subfamily H member 2).
