Extended Data Table 7 |. Functional data (Gi/o GloSensor) for mutants of the lateral channel.

Data were acquired with MT1 wild-type (WT) and mutants by using GloSensor to measure Gi/o-mediated cAMP inhibition via isoproterenol stimulation. Data represent means of EC50 (number of independent experiments in square brackets), represented as mean(pEC50) ± s.e.m. as well as EMAX shown as mean(%EMAX) ± s.e.m. %EMAX is relative to wild-type receptor in columns, and (%EMAX*) is relative to melatonin activity in rows. Mutant effects were calculated by the change in relative activity, or log(EMAX /EC50) subtracting wild-type from mutant. ND, not determined. Dose-response curves are shown in Supplementary Figure 6.
