Characterization of [3H]quipazine binding to 5-hydroxytryptamine3 receptors in rat brain membranes.

abstract：:We have demonstrated previously that D1 dopamine receptors are coupled to both Gs alpha and Go alpha. We examine here the coupling between human D5 dopamine receptors and G proteins in transfected rat pituitary GH4C1 cells. Similar to D1 receptors, cholera toxin treatment of cells reduced, but did not abolish, D5 agon...
