The potential for G-protein-coupled receptors (GPCRs) to show constitutive activity is emerging as one of the fundamental properties of GPCRs signal transduction. Indeed, of the four subtypes of E-type prostanoid (EP) receptors, the EP3 and EP4 subtypes show constitutive activity in addition to their innate ligand-dependent activation of signaling pathways. The constitutive activity of the EP3 and EP4 receptor subtypes was discovered during the initial characterizations of these receptors and may be important for setting the basal level of cellular tone in the given signaling pathway. This chapter introduces some of the methods that can be used to study the constitutive activity of the EP receptors.
