Abstract

The activities of Maxi-K channels were recorded using inside-out patches. The application of 30 nM of non-specific G protein activator, GTP $\gamma$S, to the intracellular side of the channels increases the channel activities about 3-fold, indicating that there exist some G proteins within the patch membranes to regulate the channel activities.
