Human GRM4

Figure. Concentration-dependent activation of GRM4 by L‐glutamic acid

Reporter cells were transfected with either the expression plasmid for human glutamate metabotropic receptor 4 (GRM4) or the mock plasmid and treated with various concentrations of L‐glutamic acid. Data points shown are the mean ± SEM of an experiment (n = 3), and the curve is a fit to Hill equation with an EC50 of 34 µM.
