Potassium channel, subfamily K, member 7, also known as KCNK7 or K<sub>2P</sub>7.1 is a protein which is encoded in humans by the KCNK7 gene. K<sub>2P</sub>7.1 is a potassium channel containing two pore-forming P domains. Multiple transcript variants encoding different isoforms have been found for this gene.
This gene encodes 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; It may require other non-pore-forming proteins for activity.
