Automated description from the Alliance of Genome Resources
Exhibits identical protein binding activity. Involved in cardiac muscle cell action potential and magnesium ion transport. Predicted to localize to several cellular components, including the Golgi apparatus; T-tubule; and endoplasmic reticulum. Human ortholog(s) of this gene implicated in Andersen-Tawil syndrome; familial atrial fibrillation; familial periodic paralysis; and short QT syndrome. Orthologous to human KCNJ2 (potassium voltage-gated channel subfamily J member 2).
