Description

Enables calcium ion binding activity and calcium-activated potassium channel activity. Involved in potassium ion transmembrane transport. Acts upstream of or within response to auditory stimulus. Located in membrane. Is expressed in several structures, including brain; otic vesicle; pectoral fin bud; peripheral olfactory organ; and presumptive diencephalon. Human ortholog(s) of this gene implicated in Alzheimer's disease; generalized epilepsy; and paroxysmal nonkinesigenic dyskinesia 3. Orthologous to human KCNMA1 (potassium calcium-activated channel subfamily M alpha 1).
