B. These proteins are activated after ligand binding and catalyze the exchange of GDP by GTP bound to the  subunit. to study the initial steps of G-protein activation by agonist-bound receptors in a quantitative manner, we wish to analyze the binding of radiolabeled GTP analogues.inding of [35S]GTPS to G-proteins is limited by the dissociation of GDP from the binding sites. 2. two components may contribute to this agonist-independent reaction: a. spontaneous, receptor-independent dissociation of G-protein bound GDP.
