[[http://www.uniprot.org/uniprot/KCAB2_RAT KCAB2_RAT]] Accessory potassium channel protein which modulates the activity of the pore-forming alpha subunit. [[http://www.uniprot.org/uniprot/KCNA2_RAT 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.<ref>PMID:7544443</ref>
