- Description
- Predicted to enable large conductance calcium-activated potassium channel activity. Acts upstream of or within heart contraction and response to auditory stimulus. Predicted to be located in membrane. Predicted to be active in postsynaptic membrane. Is expressed in several structures, including brain; neural rod; olfactory placode; otic vesicle; and presumptive diencephalon. Human ortholog(s) of this gene implicated in Alzheimer's disease; idiopathic generalized epilepsy; and paroxysmal nonkinesigenic dyskinesia 3. Orthologous to human KCNMA1 (potassium calcium-activated channel subfamily M alpha 1).
