Potassium channel subfamily K member 6 is a protein that in humans is encoded by the KCNK6 gene. This gene encodes K2P6.1, one of the members of the superfamily of potassium channel proteins containing two pore-forming P domains. K2P6.1, considered an open rectifier, is widely expressed. It is stimulated by arachidonic acid, and inhibited by internal acidification and volatile anaesthetics.
