Automated description from the Alliance of Genome Resources (Release 7.4.0)
Enables inward rectifier potassium channel activity. Acts upstream of or within potassium ion transmembrane transport; regulation of heart rate by cardiac conduction; and regulation of ventricular cardiac muscle cell membrane repolarization. Predicted to be located in cell surface and perinuclear region of cytoplasm. Predicted to be part of inward rectifier potassium channel complex. Predicted to be active in plasma membrane. Is expressed in several structures, including brain; early conceptus; gonad; heart; and retina. 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. Orthologous to human KCNH2 (potassium voltage-gated channel subfamily H member 2).
