GENE INFORMATION
Gene name	KCNK3 (HGNC Symbol)
Synonyms	K2p3.1, TASK, TASK-1
Description	Potassium channel, two pore domain subfamily K, member 3 (HGNC Symbol)
Entrez gene summary	This gene encodes a member of the superfamily of potassium channel proteins that contain two pore-forming P domains. The encoded protein is an outwardly rectifying channel that is sensitive to changes in extracellular pH and is inhibited by extracellular acidification. Also referred to as an acid-sensitive potassium channel, it is activated by the anesthetics halothane and isoflurane. Although three transcripts are detected in northern blots, there is currently no sequence available to confirm transcript variants for this gene. [provided by RefSeq, Aug 2008]
