Human GRPR

Figure. Concentration-dependent activation of GRPR by GRP

Reporter cells were transfected with either the expression plasmid for human gastrin releasing peptide receptor (GRPR) or the mock plasmid and treated with various concentrations of GRP. 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 1.3 nM.
