G-protein activated inward rectifier potassium channel activity
name: G-protein activated inward rectifier potassium channel activity
Description: Catalysis of the transmembrane transfer of a potassium ion by an inwardly-rectifying voltage-gated channel, where the inward rectification is due to a voltage-dependent block of the channel pore by a G protein. An inwardly rectifying current-voltage relation is one where at any given driving force the inward flow of K+ ions exceeds the outward flow for the opposite driving force.
