Automated description from the Alliance of Genome Resources
Exhibits small conductance calcium-activated potassium channel activity. Involved in membrane repolarization during atrial cardiac muscle cell action potential and potassium ion transmembrane transport. Localizes to several cellular components, including the T-tubule; Z disc; and smooth endoplasmic reticulum. Used to study Parkinson's disease. Is expressed in brain; heart; and heart ventricle. Orthologous to human KCNN2 (potassium calcium-activated channel subfamily N member 2).
