"With its particular emphasis on the constitutive activity of G-protein-coupled receptors (GPCRs)s, this book comprehensively discusses an important biological process that has not yet been covered in such depth in any other existing books on GPCRs. The international team of highly distinguished authors addresses in detail current models and concepts, to introduce medicinal chemists, physiologists, pharmacologists, and medical researchers into the advances in the understanding of GPCR activation and constitutive activity. In addition, the book provides an overview on methods of investigating constitutive GPCR activity. The text is well illustrated by selected experimental data and schemes.The chapters are all cross-referenced with each other and cover general mechanisms, methodological approaches and cover selected important GPCR systems, the consequences for drug action, including, side effects, and rational drug design for GPCR targets. The text is backed by abundant case studies and methodological advice for analysing GPCRs, covering selected pharmacologically relevant GPCR systems, the consequences for drug action, including unwanted side effects, and rational drug design for GPCR targets. It is a highly practical reference for researchers in academia and industry."

"G protein-coupled receptors (GPCRs) are one of the most important target classes in pharmacology and are the target of many blockbuster drugs. Yet only with the recent elucidation of the rhodopsin structure have these receptors become amenable to a rational drug design.Based on recent examples from academia and the pharmaceutical industry, this book demonstrates how to apply the whole range of bioinformatics, chemoinformatics and molecular modeling tools to the rational design of novel drugs targeting GPCRs."

"Main question : G protein coupled receptors are involved in highly efficient and specific activation of signalling pathways. How do GPCR signalling complexes get assembled to generate such specificity? In order to answer this question, we need to understand how receptors and their signalling partners are synthesized, folded and quality-controlled in order to generate functional proteins. Then, we need to understand how each partner of the signalling complex is selected to join a complex, and what makes this assembly possible. GPCRs are known to be able to function as oligomers, what drives the assembly into oligomers and what will be the effects of such organization on specificity and efficacy of signal transduction. Once the receptor complexes are assembled, they need to reach different locations in the cell, what drives and controls the trafficking of GPCR signalling complexes. Finally, defects in synthesis, maturation or trafficking can alter functionality of GPCRs signalling complexes, how can we manipulate the system to make it function normally again? Pharmacological chaperones may just be part of the answer to this question."
