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. |

Compound (R)-6, the most active compound, showed dopaminergic D2 activity and also had affinity for the 5HT1A serotonin receptor subtype. Its dopaminergic activity was more selective for the D2 receptor subtype (259-fold D2/D3 selectivity) than propylamine analogue (R)-2 (14-fold selectivity) or other dopaminergic standards (e.g., pergolide, lisuride, bromocriptine, and ropinirole, 1.0-, 3.4-, 8.7-, and 2.6-fold selectivities, respectively) |

The most selective compound from this group were (+)butaclamol and domperidone which showed 5-fold D3 selectivity. A number of high affinity dopamine receptor agonists, including apomorphine and bromocriptine, also failed to demonstrate selectivity. In contrast, the natural ligand dopamine and the efficacious synthetic agonists quinpirole, (+)4-propyl-9-hydroxynapthoxazine (PHNO), 2-amino-6,7-dihydroxy-1,2,3,4-tetrahydronaphthalene (6,7-ADTN), 7-OH DPAT and N-0434 showed marked apparent human dopamine D3 (hD3) receptor selectivity. In the aminotetralin series, this selectivity was observed preferentially with analogs of the 6,7-rotamer compared with compounds from the 5,6-rotamer series. Functional coupling of the hD3 receptor was investigated in a number of cell lines in which the hD3 receptor was stably expressed, including CHO cells, the neuroblastoma-glioma hybrid cell line NG108-15 and a rat 1 fibroblast cell line. |

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. |

Here we show that the neuronal calcium sensor-1 (NCS-1) can mediate desensitization of D2 dopamine receptors. Analysis of D2 receptors expressed in human embryonic kidney 293 cells indicates that NCS-1 attenuates agonist-induced receptor internalization via a mechanism that involves a reduction in D2 receptor phosphorylation. Coimmunoprecipitation experiments from striatal neurons reveal that NCS-1 is found in association with both the D2 receptor and G-protein-coupled receptor kinase 2, a regulator of D2 receptor desensitization. |

The most selective compound from this group were (+)butaclamol and domperidone which showed 5-fold D3 selectivity. A number of high affinity dopamine receptor agonists, including apomorphine and bromocriptine, also failed to demonstrate selectivity. In contrast, the natural ligand dopamine and the efficacious synthetic agonists quinpirole, (+)4-propyl-9-hydroxynapthoxazine (PHNO), 2-amino-6,7-dihydroxy-1,2,3,4-tetrahydronaphthalene (6,7-ADTN), 7-OH DPAT and N-0434 showed marked apparent human dopamine D3 (hD3) receptor selectivity. In the aminotetralin series, this selectivity was observed preferentially with analogs of the 6,7-rotamer compared with compounds from the 5,6-rotamer series. Functional coupling of the hD3 receptor was investigated in a number of cell lines in which the hD3 receptor was stably expressed, including CHO cells, the neuroblastoma-glioma hybrid cell line NG108-15 and a rat 1 fibroblast cell line. |

D3 receptors have been reported, however, to have affinities nearly 100-fold higher than those of D2 receptors for some agonists, including (+/-)-7-hydroxy-n,n-dipropyl-aminotetralin (7-OH-DPAT) and quinpirole. |

Tetraspanin-7 (TSPAN7) is expressed to variable degrees in different tissues, with the highest level in the brain, and multiple mutations in TSPAN7 have been implicated in intellectual disability. Our results showed that TSPAN7 was associated with DRD2 and reduced its surface expression by enhancing DRD2 internalization.Finally, TSPAN7 negatively affects DRD2-mediated signaling. |

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. |
