KCNN2

KCNN2, or "Potassium Calcium-Activated Channel Subfamily N Member 2," is a gene that encodes a protein belonging to the SK (small-conductance Ca^2+-activated K^+) channel family. These channels play a vital role in regulating neuronal excitability and smooth muscle contraction by allowing potassium ions to flow out of cells in response to increases in intracellular calcium levels.
