Gene: KCNMA1 (potassium calcium-activated channel subfamily M alpha 1) Homo sapiens
Symbol: KCNMA1
Name: potassium calcium-activated channel subfamily M alpha 1
Description: Exhibits actin binding activity; identical protein binding activity; and potassium channel activity. Involved in several processes, including cellular potassium ion homeostasis; negative regulation of cell volume; and smooth muscle contraction involved in micturition. Localizes to the apical plasma membrane; caveola; and voltage-gated potassium channel complex. Implicated in Alzheimer's disease and idiopathic generalized epilepsy.
Type: protein-coding
RefSeq Status: REVIEWED
