Differential effects of pertussis toxin on the muscarinic regulation of Ca2+ and K+ currents in frog cardiac myocytes
The ability of acetylcholine (ACh) to inhibit beta-agonist stimulated calcium current was compared to its ability to activate the inwardly rectifying potassium current IK(ACh) in frog atrial myocytes. As suggested by previous studies, ACh inhibited the calcium current at concentrations (EC50 = 8 nM)...
