Here we systematically quantified ligand-induced interactions between 148 GPCRs and all 11 unique G alpha subunit C-termini. For each receptor, we probed chimeric G alpha subunit activation via a transforming growth factor-alpha (TGF alpha) shedding response in HEK293 cells lacking endogenous Gq/11- and G12/13- signaling. | We defined positive coupling if any member of the subfamily scored LogRAi ≥ -1 and negative coupling if all of the members scored LogRAi < -1 (Figure 3A-B). ROC analysis gives AUC = 0.78 (Figure S4A) when considering high-confidence known coupling data and suggested a threshold of LogRAi ≥ -1.0 for defining true couplings. | The score associated to this interaction has a LogRAi ≥ -1.0. |

AR agonists stimulated binding of [35S]GTPgS to HEK 293 cell membranes containing the human a2a, a2b, or a2c ARs (Fig. 6). EPI and NE were full agonists; clonidine and oxymetazoline were partial agonists, while antagonists (e.g. rauwolscine, 5 mM) did not stimulate [35S]GTPgS incorporation (Table 3). Although a few agonists showed a great deal of selectivity for a single receptor subtype, the rank order of agonist potency for selected compounds at the human receptors (Table 3) was: a2a: Dexmedetomidine . guanabenz .

Risperidone and its active metabolite 9-OH-risperidone were compared to reference antipsychotic drugs (haloperidol, pipamperone, fluspirilene, clozapine, zotepine) and compounds under development (olanzapine, seroquel, sertindole, ORG-5222, ziprasidone) for in vitro binding to neurotransmitter receptors in brain tissue and on membranes of recombinant cells expressing cloned human receptors and for in vivo occupancy of neurotransmitter receptors in rat and guinea-pig brain following acute treatment (2 h., s.c.). The binding affinities of the compounds for various neurotransmitter receptors were measured using membrane preparations of animal brain regions and of recombinant cells expressing cloned, mostly human receptors. Receptors, tissues and cells are indicated in Table I; results are shown in Table 4A-B. |
