Background	K2P3.1 (also named TWIK-Related Acid Sensitive K+ channel, TASK-1 or KCNK3) is a member of the 2-pore (2P) domain K+ channels family that includes at least 16 members. These channels show little time or voltage dependence and are considered to be â??leakâ? or â??backgroundâ? K+ channels, thereby generating background currents which help set the membrane resting potential and cell excitation. The K2P channels have a signature topology that includes four transmembrane domains and two pore domains with intracellular N- and C termini. The functional channel is believed to be a dimer. K2P channels are regulated by diverse physical and chemical stimuli including temperature, changes in intracellular pH, mechanical stretch, inhalation anesthetics, etc. The channels can then be subclassified based in their specific activators. K2P3.1 is extremely sensitive to variations in external pH, a drop in pH from 7.7 to 6.7 will be enough to close most K2P3.1 channels. K2P3.1 channel distribution is relatively wide with high expression in the brain and heart as well as in the pancreas, kidney and lung. K2P3.1 can exist in the brain either as a homodimer or as a heterodimer with the closely related channel K2P9.1 (TASK-3). During periods of high neuronal activity a transient increase in extracellular pH has been recorded. This pH increase may stimulate K2P3.1 channel activity and hence enhance outward K+ currents. This in turn will decrease excitability in these neurons and work as a feedback mechanism.
