Official Full Name
potassium channel, subfamily K, member 2
Potassium channel subfamily K member 2 is a protein that in humans is encoded by the KCNK2 gene. This gene encodes K2P2.1, one of the members of the two-pore-domain background potassium channel protein family. This type of potassium channel is formed by two homodimers that create a channel that leaks potassium out of the cell to control resting membrane potential. The channel can be opened, however, by certain anesthetics, membrane stretching, intracellular acidosis, and heat. Three transcript variants encoding different isoforms have been found for this gene.
