Description
Product Characteristics:
pH -dependent, voltage-insensitive, background potassium channel protein. Rectification direction results from potassium ion concentration on either side of the membrane. Acts as an outward rectifier when external potassium concentration is low. When external potassium concentration is high, current is inward.
Subcellular location: Cell membrane
Synonyms: OAT1, PPH4, TASK, TBAK1, K2p3.1, TASK-1, Potassium channel subfamily K member 3, Acid-sensitive potassium channel protein TASK-1, TWIK-related acid-sensitive K(+) channel 1, Two pore potassium channel KT3.1, Two pore K(+) channel KT3.1, KCNK3, TASK1
Target Information: 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]
