Protein name

Potassium voltage-gated channel subfamily B member 2 (Voltage-gated potassium channel subunit Kv2.2)

Protein function

Voltage-gated potassium channel that mediates transmembrane potassium transport in excitable membranes, primarily in the brain and smooth muscle cells. Channels open or close in response to the voltage difference across the membrane, letting pot
