Activation of MC4R by agonist is associated with protein kinase A (PKA) and GRK phosphorylation of serine/threonine residues in the C-terminal tail of MC4R, followed by -arrestin and dynamin-dependent internalization of the receptor. Thr312 and Ser329/330 in the C-terminal tail of MC4R are potential sites for PKA |

Thr312 and Ser329/330 in the C-terminal tail of MC4R are potential sites for PKA and GRK phosphorylation and the subsequent recruitment of β-arrestin to the activated receptor. Replacement by alanine(s) of Thr312 and Ser329/330 in the C-terminal tail resulted in an impaired sequestration of mutated receptors to agonist, whereas mutations of Thr232 or Ser306 did not. This indicates that phosphorylation of these residues by kinases is critical for the internalization of MC4R. |

This study describes the development and validation of a genetically encoded ebBRET-based biosensor platform allowing live-cell mapping of GPCR-G protein coupling preferences covering 12 heterotrimeric G proteins. Profiling of 100 therapeutically relevant human GPCRs resulted in 1500 pathway-specific concentration-response curves and revealed a great diversity of coupling profiles ranging from exquisite selectivity to broad promiscuity.In our dataset, which is the first using unmodified GPCRs and Gα proteins (except for Gs), 29% of the receptors coupled to only one family, whereas others displayed more promiscuity by coupling to 2, 3, or 4 families (36%, 25%, and 10%, respectively). |

Enhanced melanocortin signaling in the hypothalamus results in both decreased food intake and increased energy expenditure. Adipose tissue derived hormone leptin induces negative energy balance by stimulating α-MSH and melanocortin-4 receptor (MC4R) (Friedman 1997, Kask et al. 1998). Increased melanocortin signaling in hypotalamus leads not only to decreased food intake but also increases sympathetic nervous system outflow to skeletal muscle, energy expenditure and physical activity |

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. |
