The Fungal Cell Wall


Book Description

This book illustrates, that the fungal cell wall is critical for the biology and ecology of all fungi and especially for human fungal pathogens. Readers will learn, that the composition of the fungal cell wall is a unique structure, which cannot be found in the human host. Consequently, the chapters outline, how the immune systems of both animals and humans have evolved to recognize conserved and unique elements of the fungal cell wall. As an application example, the authors also show, that the three-dimensional structures of the cell wall are excellent targets for the development of antifungal agents and chemotherapeutic strategies. With the combination of biological findings and medical outlooks, this volume is a fascinating read for scientists, clinicians and biomedical students.

GPI Membrane Anchors


Book Description

GPI Membrane Anchors reviews major advances in our understanding of glycosylphosphatidylinositol (GPI) membrane anchors. The book examines the GPI structure and its originality as an anchoring device, its ubiquitous distribution, the main steps of its biosynthetic pathway, and the elegant means by which a protein signals for GPI attachment. It also presents evidence for the uniqueness of GPI as a tag in intracellular traffic and as a mediator of transmembrane signaling. This volume is organized into 20 chapters and begins with a discussion of the structural requirements of a nascent protein for processing to a PI-G anchored form, with emphasis on experiments on intact cells and cell-free systems. It then turns to the mechanisms underlying signal transduction by GPI-anchored membrane proteins, the LY-6 superfamily of GPI-anchored molecules, and glycosylated-phosphatidylinositols as virulence factors in Leishmania. The reader is also introduced to the molecular biology of GPI-anchored border hydrolases, the role of GPIs and their inositolglycan derivatives in the mediation of insulin and growth factor function, and biosynthesis and cellular localization of GPI-modified glycoproteins in Saccharomyces cerevisiae. An account of electrospray mass spectrometry of a C-terminal peptide purified from the scrapie isoform of the scrapie prion protein is also given. The book concludes with a chapter on GPI-anchored recognition molecules that function in axonal fasciculation, growth, and guidance in the nervous system. This book is a valuable resource for students and researchers in the fields of cell biology and biochemistry.




The Prion Protein


Book Description

A conformational transition of the cellular prion protein (PrPC) into an aberrantly folded isoform designated scrapie prion protein (PrPSc) is the hallmark of a variety of neurodegenerative disorders collectively called prion diseases. They include Creutzfeldt-Jakob disease and Gerstmann-Stäussler-Scheinker syndrome in humans, scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle and chronic wasting disease (CWD) in free-ranging deer. In contrast to the deadly properties of misfolded PrP, PrPC seems to possess a neuroprotective activity. More-over, animal models indicated that the stress-protective activity of PrPC and the neurotoxic effects of PrPSc are somehow interconnected. In this timely book, leading scientists in the field have come together to highlight the apparently incongruous activities of different PrP conformers. The articles outline current research on celluar pathways implicated in the formation and signaling of neurotoxic and physiological PrP isoforms and delineate future research direction. Topics covered include the physiologcial activity of PrPC and its possible role as a neurotrophic factor, the finding that aberrant PrP conformers can cause neurodegeneration in the absence of infectious prion propagation, the requirement of the GPI anchor of PrPC for the neurotoxic effects of scrapie prions, the pathways implicated in the formation and neurotoxic properties of cytosolically localized PrP, the impact of metal ions on the processing of PrP, and the role of autophagy in the propagation and clearance of PrPSc. The book is fully illustrated and chapters include comprehensive reference sections. Essential reading for scientists involved in prion research.




Membrane Organization and Dynamics


Book Description

This volume brings together information on membrane organization and dynamics from a variety of spectroscopic, microscopic and simulation approaches, spanning a broad range of time scales. The implication of such dynamic information on membrane function in health and disease is a topic of contemporary interest. The chapters cover various aspects of membrane lipid and protein dynamics, explored using a battery of experimental and theoretical approaches. The synthesis of information and knowledge gained by utilizing multiple approaches will provide the reader with a comprehensive understanding of the underlying membrane dynamics and function, which will help to develop robust dynamic models for the understanding of membrane function in healthy and diseased states. In the last few years, crystal structures of an impressive number of membrane proteins have been reported, thanks to tremendous advances in membrane protein crystallization techniques. Some of these recently solved structures belong to the G protein-coupled receptor (GPCR) family, which are particularly difficult to crystallize due to their intrinsic flexibility. Nonetheless, these static structures do not provide the necessary information to understand the function of membrane proteins in the complex membrane milieu. This volume will address the dynamic nature of membrane proteins within the membrane and will provide the reader with an up-to date overview of the theory and practical approaches that can be used. This volume will be invaluable to researchers working in a wide range of scientific areas, from biochemistry and molecular biology to biophysics and protein science. Students of these fields will also find this volume very useful. This book will also be of great use to those who are interested in the dynamic nature of biological processes.
