BK channel inhibition by strong extracellular acidification

WebBK inhibition by PAX is best charac- terized by the idea that PAX gains access to the channel through the central cavity of the BK channel, and that only a single PAX molecule can interact with the BK channel at a time. The notion that PAX reaches its binding site via the central cavity and involves only a Webpotassium inhibition: arrest of the heart in the fully relaxed state as a result of potassium intoxication.
