About KCNK3

Cytogenetic location: 2p23.3 Genomic coordinates (GRCh38): 2:26,692,722-26,733,420 (from NCBI)

This gene has 1 transcript (splice variant), 272 orthologues, 14 paralogues and is associated with 3 phenotypes. Biased expression in adrenal (RPKM 48.3), placenta (RPKM 12.8) and 5 other tissues.

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]
