Activation of the atrial K(ACh) channel by the βγ subunits of G proteins or intracellular Na(+) ions depends on the presence of phosphatidylinositol phosphates

The βγ subunits of GTP-binding proteins (G(βγ)) activate the muscarinic K(+) channel (K(ACh)) in heart by direct binding to both of its component subunits. K(ACh) channels can also be gated by internal Na(+) ions. Both activation mechanisms show dependence on hydrolysis of intracellular ATP. We repo...
