Pharmacogenomic and Structural Analysis of Constitutive G Protein–Coupled Receptor Activity

Abstract: G-protein coupled receptors (GPCRs) respond to a chemically diverse plethora of signal transduction molecules. The notion that GPCRs also signal without an external chemical trigger, i.e. in a constitutive or spontaneous manner, resulted in a paradigm shift in the field of GPCR pharmacology. With the recognition of constitutive GPCR activity and the fact that GPCR binding and signaling can be strongly affected by a single point mutation, GPCR pharmacogenomics obtained a lot of attention. For a variety of GPCRs… Show more

“…We and others have demonstrated the involvement of interactions between conserved motifs LALAD (residues 70-74), Phe77 in TMD2 and NPLFY (residues 298-302), Tyr292, Phe293, Asn294, and Asn295 in TMD7 in determining AT 1 receptor functional selectivity and activation (Hunyady et al 1995a, Smit et al 2007). The ability of TMD2 to interact dynamically with TMD7 in agonist binding to receptor activation is influenced by Phe77 in TMD2 (Miura et al 2003).…”

“…Based on a large amount of experimental data, a 'global toggle switching' mechanism is suggested to occur during ligand-induced activation (Schwartz et al 2006, Smit et al 2007. Correspondingly, activation is characterized by a spatial rearrangement of the TMHs relative to one another (Scheerer et al 2008, Schertler 2008.…”

“…En règle générale, selon la résultante de l'effet sur la signalisation du ligand endogène, les composés allostériques sont classés en modulateurs allostériques positifs ou négatifs [8][9][10]. Ces effets sont parfois associés à un effet propre du type agoniste ou agoniste inverse, selon l'aptitude du composé à stabiliser la forme active ou inactive du récepteur [12]. Le mécanisme d'action des composés allostériques leur donne des propriétés modulatrices particulières sur la signalisation endogène [8][9][10].…”
