Summaries for KCNK3 Gene

Entrez Gene Summary for KCNK3 Gene

  • 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]

GeneCards Summary for KCNK3 Gene

KCNK3 (Potassium Two Pore Domain Channel Subfamily K Member 3) is a Protein Coding gene. Diseases associated with KCNK3 include Pulmonary Hypertension, Primary, 4 and Pulmonary Hypertension. Among its related pathways are Sweet Taste Signaling and Cardiac conduction. GO annotations related to this gene include protein homodimerization activity and protein C-terminus binding. An important paralog of this gene is KCNK9.

UniProtKB/Swiss-Prot for KCNK3 Gene

  • 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.

  • Pulmonary hypertension, primary, 4 (PPH4) [MIM:615344]: A rare disorder characterized by plexiform lesions of proliferating endothelial cells in pulmonary arterioles. The lesions lead to elevated pulmonary arterial pression, right ventricular failure, and death. The disease can occur from infancy throughout life and it has a mean age at onset of 36 years. Penetrance is reduced. Although familial pulmonary hypertension is rare, cases secondary to known etiologies are more common and include those associated with the appetite-suppressant drugs. {ECO:0000269 PubMed:23883380}. Note=The disease is caused by mutations affecting the gene represented in this entry.
