Abstract
The present-day model for G protein activation and the associated theo ry on how a G protein-coupled receptor may activate the G protein are summarized. Experimental data are outlined which seem not to be in acc ordance with this present-day model. An alternative molecular mechanis m for ternary complex activation is presented together with a three-di mensional model for a receptor coupled to the appropriate trimeric G p rotein. This 3D structure confirms our new molecular mechanism of acti vation.
