Human PTGER4

Figure. Concentration-dependent activation of PTGER4 by PGE2

Reporter cells were transfected with either the expression plasmid for human prostaglandin E receptor 4 (PTGER4) or the mock plasmid and treated with various concentrations of PGE2. 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 4.0 nM.

Prostanoid receptors

Prostanoid receptors are activated by the endogenous ligands prostaglandins PGD2, PGE1, PGE2, PGF, PGH2, prostacyclin [PGI2] and thromboxane A2. Differences and similarities between human and rodent prostanoid receptor orthologues, and their specific roles in pathophysiologic conditions are reviewed in [1]. Measurement of the potency of PGI2 and thromboxane A2 is hampered by their instability in physiological salt solution; they are often replaced by cicaprost and U46619, respectively, in receptor characterization studies.
