Abstract
Méthode pour mesurer la modulation de l’activation d’un récepteur couplé à une protéine G avec des analogues du GTP L’invention concerne une méthode pour déterminer la capacité d’une molécule à moduler l’activation d’un récepteur couplé à une protéine G (RCPG), ladite méthode comprenant les étapes suivantes :a) introduction, dans un premier contenant : - d’une préparation membranaire portant un ou plusieurs RCPG et une ou plusieurs protéine(s) Galpha, - d’une source de GTP non-hydrolysable ou lentement hydrolysable marqué par un premier membre d’un couple de partenaires de RET, - d’un ligand de la sous-unité alpha d’une protéine G (protéine Galpha) marqué par un second membre du couple de partenaires de RET, ledit ligand étant capable de se lier à la protéine Galpha pleine liée au GTP non-hydrolysable ou lentement hydrolysable marqué par le premier membre d’un couple de partenaires de RET, - éventuellement d’un agoniste du RCPG ; b) mesure du signal de RET émis dans le premier contenant ;c) introduction (i) dans un second contenant, des mêmes réactifs qu’à l’étape a) et de la molécule à tester ou (ii) dans le premier contenant, de la molécule à tester ;d) mesure du signal de RET émis dans le second contenant ou dans le premier contenant obtenu à l’étape c) ;e) comparaison des signaux obtenus aux étapes b) et d), une modulation du signal obtenu à l’étape d) par rapport à celui obtenu à l’étape b) indiquant que la molécule à tester est capable de moduler l’activation du RCPG.
