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. |

In order to investigate the pharmacological properties of the individual muscarinic receptors, we have transfected each of these genes into Chinese hamster ovary cells (CHO-K1) and have established stable cell lines expressing each receptor. In the present study we have examined the antagonist binding properties of each muscarinic receptor. Antagonists were chosen that had previously been proposed to be selective for muscarinic receptor subtypes and included pirenzepine, AF-DX 116, methoctramine, dicyclomine, hexohydrodifenidol, hexahydrosiladifenidol, hexocyclium, and silahexocyclium. |

We investigated whether the allosteric modulators can also increase the affinity of receptors for their agonists. Twelve agonists and five allosteric modulators were tested in experiments on membranes of CHO cells that had been stably transfected with genes for the M1-M4 receptor subtypes. Affinities of agonists for the M1–M4 receptor subtypes were determined according to the ability of the agonist to inhibit [3H]NMS binding in the presence of 0.5 mM GTP; in this way, the low affinity binding of agonists was measured.The computed pKi and nH values are summarized in Table 2. |

SB 202026 (R-(Z)-(+)-alpha-(methoxyimino)-1-azabicyclo[2.2.2] octane-3-acetonitrile) displaced [3H]-oxotremorine-M from muscarinic receptors in the rat brain with high affinity (IC50 = 14 nM), a potency similar to that of oxotremorine-M itself (IC50 = 13 nM), but exhibited low affinity for cholinergic nicotinic receptors and other neuroreceptors. In studies using cloned human muscarinic receptors, SB 202026 possessed approximately equal affinity in displacing [3H]-quinuclidinyl benzilate from all muscarinic receptor subtypes |

Antagonism of the five cloned human muscarinic cholinergic receptors expressed in CHO-K1 cells by antidepressants and antihistaminics. Competition between [‘H]QNB and the antidepressant compounds (Table 1) showed that at the ml subtype the most potent drugs were amitriptyline > dothiepin > doxepin = nortriptyline; at the m2 receptor, amitriptyline > imipramine > nortriptyline = dothiepin; at the m3 recep- tor, amitriptyline > dothiepin > nortriptyline; at the m4 receptor, amitriptyline > dothiepin > doxepin = nortrip- tyline; and at the m5 receptor, amitriptyline > doxepin > imipramine. |
