Function
[KCAB2_RAT] Accessory potassium channel protein which modulates the activity of the pore-forming alpha subunit. [KCNA2_RAT] Mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient.[1]
