Journal ArticleDOI
Seven-transmembrane receptors.
TL;DR: This paper showed that the classical models of G-protein coupling and activation of second-messenger-generating enzymes do not fully explain seven-transmembrane receptors' remarkably diverse biological actions.
Journal ArticleDOI
Transduction of receptor signals by beta-arrestins.
TL;DR: Another previously unappreciated strategy used by the receptors to regulate intracellular signaling pathways is indicated, which regulates aspects of cell motility, chemotaxis, apoptosis, and likely other cellular functions through a rapidly expanding list of signaling pathways.
Journal ArticleDOI
A ternary complex model explains the agonist-specific binding properties of the adenylate cyclase-coupled beta-adrenergic receptor.
TL;DR: In this paper, a ternary complex model was used to fit the data with high accuracy under conditions where the ligand used is either a full or a partial agonist and where the system is altered by the addition of guanine nucleotide or after treatment with group-specific reagents.
Journal ArticleDOI
Beta-arrestin-dependent formation of beta2 adrenergic receptor-Src protein kinase complexes.

TL;DR: Data suggest that beta-arrestin binding, which terminates receptor-G protein coupling, also initiates a second wave of signal transduction in which the "desensitized" receptor functions as a critical structural component of a mitogenic signaling complex.
Journal ArticleDOI
Model systems for the study of seven-transmembrane-segment receptors.
TL;DR: This paper presents a meta-analyses of the chiral signaling process and its applications in medicine and animal welfare, and investigates the role of chiral reprograming in the development of Alzheimer's disease.
