Past, present and future of vasopressin and oxytocin receptor oligomers, prototypical GPCR models to study dimerization processes
Abstract
The G protein-coupled receptors (GPCRs) play a major role in the regulation of physiological function. The emergence of the concept of GPCR oligomerization deeply modifies our understanding of their functioning. Much more than a simple association leading to an independent functioning, the GPCR oligomerization affects various steps such as membrane _targeting of the receptors, binding of ligands, coupling to the intracellular pathways and internalization. Although significant advances have been performed in proving the existence of GPCR oligomers, its physiological impact remains to be established. Vasopressin and oxytocin receptors have constituted interesting experimental models in oligomer analysis. Because of the pharmacological tools available regarding these receptors and their expression at a high level in various tissues they can constitute very promising models to study the consequences of oligomerization in physiology.
