abstract：:Human D-type prostanoid (DP) and E-type prostanoid 2 (EP2) receptors are regarded as the most closely related receptors among prostanoid receptors. Although these receptors are generated by tandem duplication, their physiological outputs often oppose one another. In the present study, we extracted mutations occurring ...
