Book Synopsis Modulation of G Protein-coupled Receptor Intracellular Trafficking and Signal Transduction by : Jessica L. Esseltine
Download or read book Modulation of G Protein-coupled Receptor Intracellular Trafficking and Signal Transduction written by Jessica L. Esseltine and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The seven transmembrane-spanning G Protein-coupled Receptor (GPCR) super family is the largest family of cell-surface receptors, comprising greater than 650 members. GPCRs represent the primary targets of most therapeutic drugs. Desensitization, endocytosis and recycling are major mechanisms of receptor regulation and intracellular trafficking of GPCRs is linked to the Rab family of small G proteins. In the present study, we examined whether multiple Rab GTPase regulate receptor trafficking through endosomal cellular compartments as a consequence of their direct association with GPCRs. We find that Rab4, Rab7 and Rab11 all bind to the last 10 amino acid residues of the angiotensin II Type 1 (AT1R) carboxyl-terminal tail. We show that the Rab GTPases compete with one another for receptor binding and that Rab4 effectively displaces Rab11 from the receptor. In contrast, Rab11 overexpression does not prevent Rab4 binding to the AT1R. Overexpression of wild-type Rab4, but not Rab11, facilitates AT1R dephosphorylation, and a constitutively active Rab4-Q67L mutant reduces AT1R desensitization and promotes AT1R resensitization. We also find that Rab8, a RabGTPase involved in the regulation of secretory/recycling vesicles, modulation of the actin cytoskeleton and cell polarity, interacts with the carboxyl-terminal tail of metabotropic glutamate receptor 1 (mGluR1a) and attenuates mGluR1a signalling and endocytosis in a protein kinase C-dependent manner. Finally, we have examined several previously uncharacterised but naturally occurring single nucleotide polymorphisms (SNPs) in mGluR1a that have been associated with cancer that may alter mGluR1a signalling. We find that SNPs found within the ligand binding domain of mGluR1a result in both decreased cell surface expression and basal inositol 1,4,5, trisphosphate formation and bias mGluR1a signalling via the ERK1/2 pathway. Additional mGluR1a SNPs localized to the mGluR1a glutamate binding site, intracellular regulatory domains and Homer binding site also result in changes in mGluR1a subcellular localization, signalling and cell morphology. Taken together, these results indicate that GPCR signalling is significantly modulated by the association of intracellular regulatory proteins that can be influenced by receptor structure.

Book Synopsis Molecular Aspects of G Protein-coupled Receptors by : Francisco Ciruela
Download or read book Molecular Aspects of G Protein-coupled Receptors written by Francisco Ciruela and published by Nova Publishers. This book was released on 2008 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the recent years, studies based on two-hybrid screens, proteomic, biochemical and cell biology approaches, have shown that intracellular domains of G protein-coupled receptors (GPCR) or heptaspanning membrane receptors (HSMRs) interact with intracellular proteins. These interactions are the basis of a protein network associated to these receptors which includes scaffolding proteins containing one or several PDZ (post-synaptic density-95, discs large, zona occludens-1) domains, signalling proteins and proteins of the cytoskeleton. The present book is focused on the emerging evidence for interactions of G protein-coupled receptors with scaffolding, cytoskeletal and signalling proteins that will play a role in the targeting, anchoring and functioning of these receptors in the plasma membrane, thus contributing to cell development and plasticity.

Book Synopsis The G Protein-Coupled Receptors Handbook by : Lakshmi A. Devi
Download or read book The G Protein-Coupled Receptors Handbook written by Lakshmi A. Devi and published by Springer Science & Business Media. This book was released on 2008-03-01 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive survey of the many recent advances in the field of G protein-coupled receptors (GPCR). The authors describe the current knowledge of GPCR receptor structure and function, the different mechanisms involved in the regulation of GPCR function, and the role of pharmacological chaperones in GPCR folding and maturation. They also present new findings about how GPCR dimerization/oligomerization modifies the properties of individual receptors and show how recent developments are leading to significant advances in drug discovery, such as the detection of ligands for orphan GPCRs. Also discussed are the most recent developments that could lead to new drug discoveries: the role of GPCRs in mediating pain, the development of receptor-type selective drugs based on the structural plasticity of receptor activation, and the identification of natural ligands of orphan GPCRs (deorphanization) as possible drug targets.

Book Synopsis Characterization of ß-arrestins Trafficking and Signaling Functions on G Protein-coupled Receptors by : Etienne Khoury
Download or read book Characterization of ß-arrestins Trafficking and Signaling Functions on G Protein-coupled Receptors written by Etienne Khoury and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The heptahelical G protein-coupled receptors (GPCRs) are the largest, most versatile superfamily of cell surface receptors and constitute the most common target for many therapeutic drugs. They participate in various physiological processes via signaling transduction, mainly induced by heterotrimeric G proteins. Following activation, these 7-transmembrane receptors recruit [beta]-arrestin for endocytosis. Beta-arrestins will directlyassociate GPCRs to several components of the endocytic machinery, such as clathrin and adaptor protein 2 (AP-2), allowing the receptor to internalize. Over the years, [beta]-arrestins were shown to also act as signaling adaptors upon binding to agonist-occupied GPCRs; however, the mechanism regulating receptor/[beta]-arrestin complexes in endosomes was not yet addressed. Based on a previous study where we showed that [beta]-arrestin serves as a scaffolding protein for several signaling effectors (e.g. MAPK) in the endosomes, we hypothesized that endosomal MAPK activity would be necessary to maintain the GPCR/[beta]-arrestin-2 complex, thus regulating receptor trafficking. Our first study revealed a putative phosphorylating MAPK motif (Thr178) in [beta]-arrestin-2 suggesting that endosomal MAPK activity is involved in such process. Using biochemical assays and FRAP (Fluorescence Recovery After Photobleaching) approach to assess the life-time of bradykinin B2 receptor (B2R)/[beta]-arrestin-2 endosomal complexes, we showed that the MAPK putative site in [beta]-arrestin-2 is involved in regulating the association between the arrestin and its receptor. The role of [beta]-arrestin-2 'hinge' domain was tested for such effect, and using arrestin mutants demonstrated distinct behaviours between [beta]-arrestin-2 species on GPCRs trafficking and agonist mediated receptor signaling. This study highlights a strong correlation between MAPKsignaling and the regulation of endosomal GPCR/[beta]-arrestin-2 interactions. In addition to the 'hinge' domain, structural studies showed that the polar core, as well as the arrestins loops, were also crucial for [beta]-arrestin activation. Based on the crystal structure of [beta]-arrestin-1, a virtual screen was then conducted in order to identify aselective pharmacological inhibitor of [beta]-arrestin-2. Results showed a unique compound, namely UM0012685 which firstly, blocked V2-vasopressin receptor (V2R) endocytosis; Secondly, inhibited [beta]-arrestin recruitment; Thirdly, decreased the stability of the receptor and [beta]-arrestin-2 endosomal complexes and finally inhibited [beta]-arrestin-2-dependent MAPK activation upon agonist stimulation of the V2R. This compound was also used as a tool to determine [beta]-arrestins trafficking function on [beta]2-adrenergic receptor ([beta]2AR) recycling. These results uncover a better understanding of the underlying mechanism regulating [beta]-arrestin in the endosomes as well as the intracellular trafficking modulation of GPCRs. Our findings also reveal a useful tool to investigate the multifunctional aspect of [beta]-arrestins in the cell." --
