Potassium channel subfamily K member 1 is a protein that in humans is encoded by the KCNK1 gene.[1][2][3]
This gene encodes K2P1.1, a member of the superfamily of potassium channel proteins containing two pore-forming P domains. The product of this gene has not been shown to be a functional channel, however, and it may require other non-pore-forming proteins for activity.[3]
