WebDec 10, 2024 · This study addresses the mechanism underlying this specificity of GIRK activation by M2Rs. K + currents and bioluminescence resonance energy transfer between labelled G proteins and GIRK show that M2Rs catalyze Gβγ subunit release at higher rates than β2ARs, generating higher Gβγ concentrations that activate GIRK and regulate other … WebThis current hyperpolarizes the cell, thus terminating the action potential. It has been shown that in chronic atrial fibrillation there an increase in this inwardly rectifying current because of constantly activated I K,ACh …
