Download or read book Peptidergic G Protein coupled Receptors written by Pierangelo Geppetti and published by IOS Press. This book was released on 1999 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Peptides are a rapidly growing class of mediators whose activity regulates homeostasis as well as pathological processes. Most of the peptide-activated receptors belong to the superfamily of 7 transmembrane domain receptors coupled to G proteins. Peptides of different sizes (from a few to more than 100 aminoacids) activate peptidergic receptors by interacting at specific sites, that often differ from those where antagonists bind. Other receptors are activated by proteases that, by cleaving the receptor extracellular region, unmask a tethered ligand. G protein-coupled receptors for chemokines represent the way of entry of the HIV virus in target cells. The great impact of non peptide agonist/antagonists in current and future medicine reflects these large variety of functions and modes of activation of peptidergic G protein-coupled receptors.

Download or read book Regulatory Peptides and Cognate Receptors written by Dietmar Richter and published by Springer Science & Business Media. This book was released on 2013-06-05 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last two decades, our knowledge on regulatory peptides and their cognate receptors, most of which are members of the seven transmembrane receptor families, has increased enormously. Regulatory peptides are small proteins which, besides their hormonal functions in regulating cellular metabolism in various tissues, may also act as neurotransmitters, and thus they often carry the prefix "neuro." Many of the cognate receptors involved in transducing the peptidergic signal across the cell membrane via a family of G proteins exist in multiple forms, the number of which frequently exceeds that of the corresponding peptide ligands. In this book, various peptide-receptor systems are discussed, e.g. CRF, somatostatin, TRH, opioid peptides, vasopressin, and oxytocin. It also discusses new strategies such as "reverse physiology" to uncover new peptides and orphan receptors.

This book was released on 2016-12-13 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Document from the year 2016 in the subject Biology - Evolution, grade: -, Agricultural University of Tirana, language: English, abstract: G protein-coupled receptors (GPCRs) are members of a large protein family that share common structural motifs, including seven transmembrane helices, and play pivotal roles in cell-to-cell communications and in the regulation of cell functions. GPR103 is an orphan GPCR that shows similarities with orexin, neuropeptide FF, and cholecystokinin receptors. In humans, 26RFa/QRFP has been found to be an endogenous ligand for the orphan receptor, GPR103 and it is one of the RFamide peptides, which have been shown to exert important neuroendocrine, behavioural, sensory and autonomic functions. All the information we have till know couldn’ be available if we didn’t know the evolution of this important proteins and the relative interactions, which were discovered recently to be important for the regulation of locomotor activity, sleep and these neuropeptides and receptors exert neuroprotective effect in Alzheimer’s Disease. Anyway, there is a long way to be walked on, because there is a need of additional information, while studing the molecular evolution of these proteins and peptides. What is the Molecular Evolution? In the First chapter the readers can find all about this branch of science and the problems this branch had overcomed in order to bring to the scientific community the molecularisation of the evolution concepts. In the following chapter to the readers is presented a descriptive overview of G-proteins and G-protein coupled receptor. In the other chapters it is also presented 26RFA/QRFP and pyroglutamylated RFamide peptide receptor (QRFPR) molecular evolution, where it is described the molecular phylogeny and the functional implication. It is even shown the unique study regarding the presence on natural selection (positive or negative selection) during the evolution of QRFPRs in mammals and fish species. In the end of the book are shown the recent important finding regarding the function and the role of QRFP and its receptor, together with the experimental approach applied to zebrafish and rodents. Anyway, it is imperative to mention that all the available knowledge from experiments to these animals can be useful for the curation of disorders and other deseases like Alzheimer’s Disease, only if we could understand well their molecular evolution.
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.

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.
