RGS6/Gβ5 complex accelerates I(KACh) gating kinetics in atrial myocytes and modulates parasympathetic regulation of heart rate

RATIONALE: The parasympathetic reduction in heart rate (HR) involves the sequential activation of m2 muscarinic cholinergic receptors (m(2)R), pertussis toxin-sensitive (Gi/o) heterotrimeric G proteins, and the atrial potassium channel I(KACh). Molecular mechanisms regulating this critical signal tr...
