Potassium Channel

Potassium Channels. K+ channels are membrane proteins that allow rapid and selective flow of K+ ions across the cell membrane, and thus generate electrical signals in cells. Voltage-gated K+ channels (Kv channels), present in all animal cells, open and close upon changes in the transmembrane potential.
