Automated description from the Alliance of Genome Resources (Release 3.2)
Predicted to have inward rectifier potassium channel activity and voltage-gated potassium channel activity involved in atrial cardiac muscle cell action potential repolarization. Predicted to be involved in cardiac conduction; potassium ion import across plasma membrane; and regulation of ion transmembrane transport. Predicted to localize to T-tubule; external side of plasma membrane; and voltage-gated potassium channel complex. Is expressed in several structures, including central nervous system; heart; intestine; liver lobe; and placenta. Human ortholog(s) of this gene implicated in atrial fibrillation; long QT syndrome 13; and primary hyperaldosteronism. Orthologous to human KCNJ5 (potassium inwardly rectifying channel subfamily J member 5).
