Guidebook to Molecular Chaperones and Protein-Folding Catalysts


Book Description

The precise shape of a protein is a crucial factor in its function. How do proteins become folded into the right conformation? Molecular chaperones and protein folding catalysts bind to developing polypeptides in the cytoplasm and ensure correct folding and transport. This Guidebook catalogues the latest information on nearly 200 of these molecules, including the important class of heat shock proteins; each entry is written by leading researchers in the field.




Molecular Chaperones and Folding Catalysts


Book Description

One of the most intriguing discoveries in molecular biology in the last decade is the existence of an evolutionary conserved and essential system, consisting of molecular chaperones and folding catalysts, which promotes the folding of the proteins in the cell. This text summarizes our current knowledge of the cellular roles, the regulation and the mechanism of action of this system. It has a broad scope, covering cell biological, genetic and biochemical aspects of protein folding in cells from bacteria to man. Particularly appropriate to researchers working in basic and applied aspects of molecular medicine, this volume should also prove useful as an up-to-date reference book and as a textbook for specialized university courses.







Protein Folding in the Cell


Book Description

This volume of Advances in Protein Chemistry provides a broad, yet deep look at the cellular components that assist protein folding in the cell. This area of research is relatively new--10 years ago these components were barely recognized, so this book is a particularly timely compilation of current information. Topics covered include a review of the structure and mechanism of the major chaperone components, prion formation in yeast, and the use of microarrays in studying stress response. Outlines preceding each chapter allow the reader to quickly access the subjects of greatest interest. The information presented in this book should appeal to biochemists, cell biologists, and structural biologists.




Heat Shock Proteins in Cancer


Book Description

Heat shock proteins are emerging as important molecules in the development of cancer and as key targets in cancer therapy. These proteins enhance the growth of cancer cells and protect tumors from treatments such as drugs or surgery. However, new drugs have recently been developed particularly those targeting heat shock protein 90. As heat shock protein 90 functions to stabilize many of the oncogenes and growth promoting proteins in cancer cells, such drugs have broad specificity in many types of cancer cell and offer the possibility of evading the development of resistance through point mutation or use of compensatory pathways. Heat shock proteins have a further property that makes them tempting targets in cancer immunotherapy. These proteins have the ability to induce an inflammatory response when released in tumors and to carry tumor antigens to antigen presenting cells. They have thus become important components of anticancer vaccines. Overall, heat shock proteins are important new targets in molecular cancer therapy and can be approached in a number of contrasting approaches to therapy.




RNA Chaperones


Book Description

This book provides a wide spectrum of methods to study RNA chaperones in vitro, at the single molecule level, and protocols useful for cell-based assays. Beginning with a section on a number of bacterial proteins for study, the volume also explores proteins from eukaryotic cells and how to delve into the complex interactions between RNA chaperones and the folding and unfolding of proteins. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, RNA Chaperones: Methods and Protocols serves as an ideal guide for scientists and students interested in RNA biology and RNA chaperones. Chapter 3 is available Open Access under a CC-BY 4.0 license via link.springer.com.




Post-Transcriptional Control of Gene Expression in Plants


Book Description

A recent volume of this series (Signals and Signal Transduction Pathways in Plants (K. Palme, ed.) Plant Molecular Biology 26, 1237-1679) described the relay races by which signals are transported in plants from the sites of stimuli to the gene expression machinery of the cell. Part of this machinery, the transcription apparatus, has been well studied in the last two decades, and many important mechanisms controlling gene expression at the transcriptional level have been elucidated. However, control of gene expression is by no means complete once the RNA has been produced. Important regulatory devices determine the maturation and usage of mRNA and the fate of its translation product. Post-transcriptional regulation is especially important for generating a fast response to environmental and intracellular signals. This book summarizes recent progress in the area of post-transcriptional regulation of gene expression in plants. 18 chapters of the book address problems of RNA processing and stability, regulation of translation, protein folding and degradation, as well as intracellular and cell-to-cell transport of proteins and nucleic acids. Several chapters are devoted to the processes taking place in plant organelles.




Encyclopedia of Signaling Molecules


Book Description

Biological processes are driven by complex systems of functionally interacting signaling molecules. Thus, understanding signaling molecules is essential to explain normal or pathological biological phenomena. A large body of clinical and experimental data has been accumulated over these years, albeit in fragmented state. Hence, systems biological approaches concomitant with the understanding of each molecule are ideal to delineate signaling networks/pathways involved in the biologically important processes. The control of these signaling pathways will enrich our healthier life. Currently, there are more than 30,000 genes in human genome. However, not all the proteins encoded by these genes work equally in order to maintain homeostasis. Understanding the important signaling molecules as completely as possible will significantly improve our research-based teaching and scientific capabilities. This encyclopedia presents 350 biologically important signaling molecules and the content is built on the core concepts of their functions along with early findings written by some of the world’s foremost experts. The molecules are described by recognized leaders in each molecule. The interactions of these single molecules in signal transduction networks will also be explored. This encyclopedia marks a new era in overview of current cellular signaling molecules for the specialist and the interested non-specialist alike During past years, there were multiple databases to gather this information briefly and very partially. Amidst the excitement of these findings, one of the great scientific tasks of the coming century is to bring all the useful information into a place. Such an approach is arduous but at the end will infuse the lacunas and considerably be a streamline in the understanding of vibrant signaling networks. Based on this easy-approach, we can build up more complicated biological systems.




Macromolecular Protein Complexes II: Structure and Function


Book Description

This book follows on from Volume 83 in the SCBI series (“Macromolecular Protein Complexes”), and addresses several important topics (such as the Proteasome, Anaphase Promoting Complex, Ribosome and Apoptosome) that were not previously included, together with a number of additional exciting topics in this rapidly expanding field of study. Although the first SCBI Protein Complex book focused on soluble protein complexes, the second (Vol. 87)addressed Membrane Complexes, and the third (Vol. 88) put the spotlight on Viral Protein and Nucleoprotein Complexes, a number of membrane, virus and even fibrillar protein complexes have been be considered for inclusion in the present book. A further book is also under preparation that follows the same pattern, in an attempt to provide a thorough coverage of the subject.
