 Calcium-activated potassium channel subunit alpha-1

Calcium-activated potassium channel subunit alpha-1 is a protein that plays a crucial role in regulating potassium ion (K+) flow across cell membranes. It is encoded by the **KCNMA1** gene in humans. The protein is part of the large conductance calcium-activated potassium (BK) channel family, which is known for its ability to be activated by both intracellular calcium ions and membrane depolarization.
