WebApr 13, 2016 · Abstract. G protein gated inward rectifier potassium (GIRK) channels are gated by direct binding of G protein beta-gamma subunits (Gβγ), signaling lipids, and intracellular Na +. In cardiac pacemaker cells, hetero-tetramer GIRK1/4 channels and homo-tetramer GIRK4 channels play a central role in parasympathetic slowing of heart rate. WebAug 15, 2000 · As illustrated in Fig. 5B, β5γ2 inhibited both basal and agonist-induced GIRK1,2 channel currents in the G1,2m4 cell line, a stable cell line that expresses GIRK1,2 channels and the m4-muscarinic receptor . The agonist-independent basal conductance was reduced by ≈36% in cells transfected with β5γ2 (from 2.2 ± 0.3 nS to 1.4 ± 0.2 nS ...
