Human RXFP1

Figure. Concentration-dependent activation of RXFP1 by relaxin‐1

Reporter cells were transfected with either the expression plasmid for human relaxin family peptide receptor 1 (RXFP1) or the mock plasmid and treated with various concentrations of relaxin‐1. 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 10 nM.
