Human P2RY2

Figure. Concentration-dependent activation of P2RY2 by UTP

Reporter cells were transfected with either the expression plasmid for human purinergic receptor P2Y2 (P2RY2) or the mock plasmid and treated with various concentrations of UTP. 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 1.5 µM.
