Summary:

The resting membrane potential of excitable cells is determined by leak conductances predominantly mediated by KCNK and two-pore-domain potassium channels (K2P). K2P channels are characterized by the presence of two pore forming regions and four trans-membrane spanning (4TMS) regions in each channel subunit and form functional dimers. These channels are essential for the production of background leak type potassium currents that act to regulate resting membrane potential and levels of cellular excitability. The TWIKrelated acid-sensitive K+ channel 1 (K2P3.1 or TASK-1) is a member of the K2P channel family and is encoded by the KCNK3 gene. TASK-1 is ubiquitously expressed throughout the CNS but also in other tissues such as in the heart, adrenal gland, lung, pancreas,kidney, intestine and prostate. TASK-1 has been implicated in atrial fibrillation (AF) pathophysiology and was suggested as an atrial-selective antiarrhythmic drug target. TASK-1 is activated by extracellular acidosis and inhibited by anandamide and by local anesthetics including bupivicaine. Volatile general anestethics such as halothan and xenon stimulate TASK-1.
