Potassium channel, subfamily K, member 17, also known as KCNK17, is a human gene.^[1]

This gene encodes one of the members of the superfamily of potassium channel proteins containing two pore-forming P domains. This open channel, primarily expressed in the pancreas, is activated at alkaline pH.^[1]
