Download or read book G Protein Signaling Mechanisms in the Retina written by Kirill A. Martemyanov and published by Springer. This book was released on 2014-09-04 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of this volume is to provide a focused analysis of the function of the G protein-coupled signaling pathways that operate in the interconnected network of retinal neurons as they detect and encode the information carried by light. The organization of this volume will generally follow the path of signal flow in the retina. First we will describe recent advances in understanding the phototransduction cascade of rod and cone photoreceptors, which use signaling cascade based on the GPCR rhodopsin to transduce incident light into neural activity. Chapters will be devoted to unique specializations of the two major types of photosensitive cells that comprise the predominant input for our spatial and color vision. Subsequently, the mechanisms of synaptic information encoding by retinal ON bipolar cells will be described, where the GPCR mGluR6 plays a fundamental role. Chapters in this section will examine macromolecular organization of the mGluR6 signaling pathway as well as current understanding of its function. The functional characteristics of this signaling mechanism will be explored in detail. Additionally, this section will cover the role of dopamine receptors in modulating signal transmission between photoreceptors and ON-bipolar cells. Finally, chapters will be focused on the output neurons of the inner retina, ganglion cells, where the components of the emerging GPCR melanopsin cascade in intrinsically photosensitive ganglion cells will be detailed. Collectively these mechanisms allow the retina to represent visual space over a wide range of light intensities.

Download or read book Principles of Endocrinology and Hormone Action written by Antonino Belfiore and published by Springer. This book was released on 2018-02-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides comprehensive coverage of the current knowledge of the physiology of the endocrine system and hormone synthesis and release, transport, and action at the molecular and cellular levels. It presents essential as well as in-depth information of value to both medical students and specialists in Endocrinology, Gynecology, Pediatrics, and Internal Medicine. Although it is well established that the endocrine system regulates essential functions involved in growth, reproduction, and homeostasis, it is increasingly being recognized that this complex regulatory system comprises not only hormones secreted by the classic endocrine glands but also hormones and regulatory factors produced by many organs, and involves extensive crosstalk with the neural and immune system. At the same time, our knowledge of the molecular basis of hormone action has greatly improved. Understanding this complexity of endocrine physiology is crucial to prevent endocrine disorders, to improve the sensitivity of our diagnostic tools, and to provide the rationale for pharmacological, immunological, or genetic interventions. It is such understanding that this book is designed to foster.

Download or read book Mechanisms of G Protein Regulation by RGS Proteins and Small Molecule Inhibitors written by Stanley Michinobu Kanai and published by . This book was released on 2017 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: G protein coupled receptors transduce diverse extracellular signals like hormones, neurotransmitters, and photons to specific cellular responses through heterotrimeric G proteins. G proteins activate numerous effectors and signal transduction pathways, and therefore the regulation of G proteins is crucial for faithful propagation of specific cellular and physiological responses. A better understanding of the mechanisms that regulate G proteins should provide new insight into signaling pathways that govern healthy and disease states, and also provide opportunities for discovery of novel therapeutic targets.Regulator of G protein signaling (RGS) proteins are crucial regulators of G proteins, for they control amplitude and duration of G protein signaling responses. RGS2 is particularly important because it is associated with many physiological and disease processes. A key concept that has emerged is that physiological and disease processes are extremely sensitive to even modest changes in RGS2 expression levels. The goals of this dissertation were to investigate the mechanism that controls RGS2 levels and to determine how dynamic RGS2 levels affect GPCR signaling. The particular focus was on the ubiquitin proteasome pathway (UPP), which is one of the key mechanisms that control RGS2 expression levels. Rather than looking for components of the UPP that recognize and degrade RGS2, a comprehensive analysis was performed on the RGS2 N-terminal domain to identify signals required for degradation. This analysis revealed a novel bipartite hydrophobic motif that is required for degradation. Intriguingly, deletion of these hydrophobic motifs did not abrogate binding with E3 ligases associated with RGS2 degradation, suggesting additional mechanisms are involved. The effect of UPP mediated degradation of RGS2 on regulation of GPCR signaling was also explored. Using a cell based, kinetically resolved, GPCR reporter assay, it was demonstrated that proteasome degradation of RGS2 dynamically regulates GPCR signaling, influencing both agonist efficacy and the rate of receptor resensitization.G protein signaling pathways also can be modulated by small molecule inhibitors. YM-254890 and FR900359 are a class of small molecule inhibitors for G proteins that are selective and cell permeable. They are promising research tools and leads for therapeutic agents, but the exact molecular mechanism of action of these inhibitors is not known. The second part of the dissertation describes early stages of a study that aims to elucidate the mechanism of action of YM and FR. Preliminary results that support an allosteric model of inhibition are reported, followed by a discussion of future work that will further test this model.
Download or read book GPCR Signalling Complexes Synthesis Assembly Trafficking and Specificity written by Denis J. Dupré and published by Springer Science & Business Media. This book was released on 2012-11-19 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
