Les récepteurs couplés aux protéines G (RCPGs) constituent la plus grande classe de récepteurs membranaires impliqués dans la transmission des signaux extracellulaires. Traditionnellement, la transmission de la signalisation par les RCPGs implique l’activation d’une protéine G hétéro-trimérique qui pourra à…
