P2Y2 RECEPTOR - Chalmers Open Digital Repository

GPCR spans the cell membrane seven times and transduces extracellular stimuli from the binding of cell surface ligands into intracellular second messengers. These second messengers are known as the heterotrimeric guanine nucleotide-binding protein (G proteins), which consists of G α, G β, and G γ subunits . Signaling bias is the propensity for some agonists to preferentially stimulate G protein–coupled receptor (GPCR) signaling through one intracellular pathway versus another. We previously identified a G protein–biased agonist of the D 2 dopamine receptor (D2R) that results in impaired β-arrestin recruitment.

G proteins are specialized proteins with the ability to bind the nucleotides guanosine triphosphate (GTP) and guanosine diphosphate (GDP). There are two models for GPCR-G Protein interactions: 1) ligand-GPCR binding first, then binding to G Proteins; 2) "Pre-coupling" of GPCRs and G Proteins before ligand binding (review Oldham WM and Hamm HE, 2008). These in turn activate effector enzymes or ion channels.

Author information: (1)Institut de Génomique Fonctionnelle, Universités de Montpellier, CNRS UMR 5203, 141 rue de la Cardonille, Montpellier CEDEX 5, F-34094, France. Our findings uncover important structural aspects to better understand the framework of GPCR-βarr interaction and biased signaling. INTRODUCTION The interaction of β-arrestins (βarrs) with G protein–coupled receptors (GPCRs) is a versatile mechanism to regulate agonist-induced downstream signaling and trafficking of these receptors ( 1 – 3 ).
