KCNK5

This gene encodes one of the members of the superfamily of potassium channel proteins containing two pore-forming P domains. The message for this gene is mainly expressed in the cortical distal tubules and collecting ducts of the kidney. The protein is highly sensitive to external pH and this, in combination with its expression pattern, suggests it may play an important role in renal potassium transport. [provided by RefSeq]

potassium channel, subfamily K, member 5

pH-dependent, outwardly rectifying potassium channel (PubMed:9812978).
Outward rectification is lost at high external K(+) concentrations (PubMed:9812978).
