The immediate trigger for the dissociation of the α and βγ subunits of the G-protein is the binding of GTP to the α subunit. This event follows the activation of the G-protein by a receptor, leading to the exchange of GDP for GTP on the α subunit, which then causes the dissociation of the α subunit from the βγ subunits.
