WebCalcium-activated potassium channels are potassium channels gated by calcium, [1] or that are structurally or phylogenetically related to calcium gated channels. They were first discovered in 1958 by Gardos who saw that calcium levels inside of a cell could affect the permeability of potassium through that cell membrane. WebB. Alexander Yi, Lily Y. Jan, in Encyclopedia of the Human Brain, 2002 III.B Ion Channel Assembly. Ion channels are typically assembled from many subunits that form the pore-lining structure. The number of subunits that form ion channels varies from subfamily to subfamily. For example, four subunits of voltage-gated potassium channels assemble to …
