    Abstract The ability of structurally distinct ligands to "bias" G protein-coupled receptor signaling affords the opportunity to tailor efficacy to suit specific therapeutic needs. Furness et al. demonstrate that ligand structure controls not only which effectors are activated, but also the way they are activated and the kinetics of downstream signaling.

    Abstract Conventional orthosteric drug development programs targeting G protein-coupled receptors (GPCRs) have focused on the concepts of agonism and antagonism, in which receptor structure determines the nature of the downstream signal and ligand efficacy determines its intensity. Over the past decade, the emerging paradigms of "pluridimensional efficacy" and "functional selectivity" have revealed that GPCR signaling is not monolithic, and that ligand structure can "bias" signal output by stabilizing active receptor states in different proportions than the native ligand. Biased ligands are novel pharmacologic entities that possess the unique ability to qualitatively change GPCR signaling, in effect creating "new receptors" with distinct efficacy profiles driven by ligand structure. The promise of biased agonism lies in this ability to engender "mixed" effects not attainable using conventional agonists or antagonists, promoting therapeutically beneficial signals while antagonizing deleterious ones. Indeed, arrestin pathway-selective agonists for the type 1 parathyroid hormone and angiotensin AT1 receptors, and G protein pathway-selective agonists for the GPR109A nicotinic acid and μ-opioid receptors, have demonstrated unique, and potentially therapeutic, efficacy in cell-based assays and preclinical animal models. Conversely, activating GPCRs in "unnatural" ways may lead to downstream biological consequences that cannot be predicted from prior knowledge of the actions of the native ligand, especially in the case of ligands that selectively activate as-yet poorly characterized G protein-independent signaling networks mediated via arrestins. Although much needs to be done to realize the clinical potential of functional selectivity, biased GPCR ligands nonetheless appear to be important new additions to the pharmacologic toolbox.

    Abstract Our growing appreciation of the pluridimensionality of G protein-coupled receptor (GPCR) efficacy, coupled with the phenomenon of orthosteric ligand "bias," offers the prospect of drugs that selectively modulate different aspects of GPCR function for therapeutic benefit. As the best-studied non-G protein effectors, arrestins have been shown to mediate a wide range of GPCR signals, and arrestin pathway-selective ligands have been identified for several receptors. When viewed from the perspective of short term in vitro assays, such "biased" agonists appear to activate a subset of the response profile produced by a conventional agonist. Yet, when examined in vivo, the limited data available suggest that biased ligand effects can diverge from their conventional counterparts in ways that cannot be predicted from their in vitro efficacy profile. While some widely conserved arrestin-regulated biological processes are becoming apparent, what is lacking at present is a rational framework for relating the in vitro efficacy of a "biased" agonist to its in vivo actions that will aid drug discovery programs in identifying "biased" ligands with the desired biological effects.

    Abstract The arrestins are ubiquitously expressed adaptor proteins that orchestrate transmembrane signaling cascades triggered by the 7-transmembrane G protein-coupled receptors. While originally discovered as proteins that block receptor-G protein coupling, arrestins are now appreciated for their expanding repertoire of dynamic protein interactions and cellular functions.

    Abstract Information contained in the structure of extracellular ligands is transmitted across the cell membrane through allosterically induced changes in G protein-coupled receptor (GPCR) conformation that occur upon ligand binding. These changes, in turn, are imprinted upon intracellular effectors like arrestins and help determine which of its many functions are performed. Intramolecular fluorescein arsenical hairpin (FlAsH) bioluminescence resonance energy transfer (BRET), in which both the fluorescence donor and acceptor are contained within the same protein, can be used to report on activation-induced changes in protein conformation. Here, we describe a method using a series of Rluc-arrestin3-FlAsH-BRET biosensors to measure stimulus-induced changes in arrestin conformation in live cells. Each Rluc-arrestin3-FlAsH-BRET construct contains an N-terminal Renilla luciferase fluorescence donor that excites a fluorescent arsenical targeted to a different position within the protein by mutational insertion of a tetracysteine tag motif. Changes in net BRET upon GPCR stimulation can thus be viewed from multiple vantage points within the protein and used to develop an arrestin3 "conformational signature" that is receptor- and ligand-specific. This method can be used to determine how differences in GPCR and ligand structure influence information transfer across the plasma membrane and to classify GPCRs and/or ligands based on their capacity to induce different arrestin3 activation modes.
