Wiley-Blackwell Identification and Expression of G Protein–Coupled Receptors (Receptor Biochemistry and Methodology)

Product Description Receptors are sites and system within the brain and central nervous system that act as links in the information processing chains. G-protein receptors (GPCRs), the biggest single class of receptors in biology, are the primary effectors of the senses of smell and sight. A large number of current drugs and addictive agents can block and/or mimic these GPCRs. This manual reflects the increased focus on approaches to ligand identification by emphasizing expression, rather than primary cloning strategies. Each contributor provides detailed protocols for executing various strategies and offers judgments as to what approaches are, and are not useful. From the Back Cover IDENTIFICATION AND EXPRESSION OF G PROTEIN-COUPLED RECEPTORSedited by Kevin R. Lynch The past decade has seen tremendous advances in the study of G protein-coupled receptors (GPCRs), including the molecular cloning and identification of more than 100 GPCR genes. But while GPCRs serve as targets for more than 300 medicines in the modern pharmacopoeia, the shrinking pool of known ligands and the continuing discovery of orphan GPCR genes have underscored the need for new approaches to ligand identification.Identification and Expression of G Protein-Coupled Receptors addresses this new direction in GPCR biochemistry--offering a definitive laboratory bench manual that emphasizes expression over primary cloning strategies. In a series of expert contributions by well-known researchers, this book provides detailed protocols for various expression systems--from bacteria to mammalian cells--as well as straightforward opinions on the advantages and shortcomings of each approach.Topics covered include: *Homology screening and the polymerase chain reaction in the cloning of GPCR genes *Cloning of GPCRs using mammalian cell expression *GPCR informatics and the orphan problem *The use of Xenopus laevis oocytes for the study of GPCRs *Stable expression of GPCRs in mammalian cells *Heterologous expression in primary cell cultures *Expression of GPCRs in Escherichia coli *Large scale expression and purification of GPCRs in mammalian cells *High-level expression of GPCRs in the Baculovirus/Sf9 cell expression system *Expression of GPCRs in Drosophila Schneider 2 cells *Methods for genetic analysis and ligand identification using heterologous GPCRs expressed in Saccharomyces cerevisiae.Supplemented with numerous photographs and illustrations, Identification and Expression of G Protein-Coupled Receptors is important reading for biochemists, pharmacologists, neuro-scientists, structural biologists, and anyone involved in GPCR-based research. It delivers a wealth of useful advice, practical tips, and invaluable insight into trends at the cutting-edge of current research.Also in this series: Receptor Localization: Laboratory Methods and Procedures.
