in order to clarify the question of whether the modulatory effects of cations on dopamine receptor affinities are brought about by shifts in the equilibrium of receptor - g protein - coupling , it was investigated whether mono- and divalent cations were still able to modulate rat striatal d1 and d2 receptor affinities after selective inactivation of the g-proteins linked to the two receptors .
