Potassium channel subfamily K member 1 is a protein that in humans is encoded by the KCNK1 gene.^[5][6][7]

This gene encodes K_2P1.1, 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.^[7]
