Potassium channel subfamily K member 3 is a protein that in humans is encoded by the KCNK3 gene.This gene encodes K2P3.1 one of the members of the superfamily of potassium channel proteins containing two pore-forming P domains. K2P3.1 is an outwardly rectifying channel that is sensitive to changes in extracellular pH and is inhibited by extracellular acidification. Also referred to as an acid-sensitive potassium channel it is activated by the anesthetics halothane and isoflurane.
