Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables small conductance calcium-activated potassium channel activity. Involved in membrane repolarization during atrial cardiac muscle cell action potential; modulation of chemical synaptic transmission; and potassium ion transmembrane transport. Located in several cellular components, including T-tubule; Z disc; and smooth endoplasmic reticulum. Is active in glutamatergic synapse and postsynaptic membrane. Is expressed in brain; heart; and heart ventricle. Used to study Parkinson's disease. Human ortholog(s) of this gene implicated in dystonia. Orthologous to human KCNN2 (potassium calcium-activated channel subfamily N member 2).
