This book was released on 2012-12-06 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein degradation has been identified as a major mechanism for the regulation of cellular functions. Not surprisingly, its deregulation is implied in almost any pathological condition. This book describes how aged proteins are eliminated during cell metabolism, how cell proliferation is regulated by protein degradation and how its deregulation can contribute to the development of cancer, how protein degradation is modified during normal and abnormal aging, in particular with regard to Alzheimer's disease and other degenerative diseases of the brain and central nervous system. Attempts aiming at correcting these pathologies by interfering with deviations of the normal pathway of protein degradation are also treated.

Available in PDF, EPUB and Kindle. Book excerpt: This volume brings together a set of reviews that provide a summary of our current knowledge of the proteolytic machinery and of the pathways of protein breakdown of prokaryotic and eukaryotic cells. Intracellular protein degradation is much more than just a mechanism for the removal of incorrectly folded or damaged proteins. Since many short-lived proteins have important regulatory functions, proteolysis makes a significant contribution to many cellular processes including cell cycle regulation and transciptional control. In addition, limited proteolytic cleavage can provide a rapid and efficient mechanism of enzyme activation or inactivation in eukaryotic cells. In the first chapter, Maurizi provides an introduction to intracellular protein degradation, describes the structure and functions of bacterial ATP-dependent proteases, and explores the relationship between chaperone functions and protein degradation. Many of the principles also apply to eukaryotic cells, although the proteases involved are often not the same. Interestingly, homologues of one of the bacterial proteases, Ion protease, have been found in mitochondria in yeast and mammals, and homologues of proteasomes, which are found in all eukaryotic cells (see below), have been discovered in some eubacteria. Studies of proteolysis in yeast have contributed greatly to the elucidation of both lysosomal (vacuolar) and nonlysosomal proteolytic pathways in eukaryotic cells. Thumm and Wolf (chapter 2) describe studies that have elucidated the functions of proteasomes in nonlysosomal proteolysis and the contributions of lysosomal proteases to intracellular protein breakdown. Proteins can be selected for degradation by a variety of differen mechanisms. The ubiquitin system is one complex and highly regulated mechanism by which eukaryotic proteins are targetted for degradation by proteosomes. In chapter 3, Wilkinson reviews the components and functions of the ubiquitin system and considers some of the known substrates for this pathway which include cell cycle and transcriptional regulators. The structure and functions of proteosomes and their regulatory components are described in the two subsequent chapters by Tanaka and Tanahashi and by Dubiel and Rechsteiner. Proteasomes were the first known example of threonine proteases. They are multisubunit complexes that, in addition to being responsible for the turnover of most short-lived nuclear and cytoplasmic protein, are also involved in antigen processing for presentation by the MHC class I pathway. Recent studies reviewed by McCracken and colleagues (chapter 6) lead to the exciting conclusion that some ER-associated proteins are degraded by cytosolic proteasomes. Lysosomes are responsible for the degradation of long-lived proteins and for the enhanced protein degradation observed under starvation conditions. In chapter 7 Knecht and colleagues review the lysosomal proteases and describe studies of the roles of lysosomes and the mechanisms for protein uptake into lysosomes. Methods of measuring the relative contribution of different proteolytic systems (e.g., ubiquitin-proteasome pathway, calcium-dependent proteases, lysosomes) to muscle protein degradation, and the conclusions from such studies, are reviewed by Attai and Taillinder in the following chapter. Finally, proteases play an important role in signaling apoptosis by catalyzing the limited cleavage of enzymes. Mason and Beyette review the role of the major players, caspases, which are both activated by and catalyze limite proteolysis, and also consider the involvement of other protoelytic enzymes in this pathway leading cell death.

Download or read book Ubiquitin Proteasome System written by Matthew Summers and published by BoD – Books on Demand. This book was released on 2019-06-19 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human ubiquitin proteasome system (UPS) is comprised of nearly 1000 proteins. Although originally identified as a mechanism of protein destruction, the UPS has numerous additional functions and mediates central signaling events in myriad processes involved in both cellular and organismal health and homeostasis. Numerous pathways within the UPS are implicated in disease, ranging from cancer to neurodegenerative diseases such as Parkinson's. The goal of this book is to deliver a collection of synopses of current areas of UPS research that highlights the importance of understanding the biology of the UPS to identify disease-relevant pathways, and the need to elucidate the molecular machinations within the UPS to develop methods for therapeutic modulation of these pathways.
Download or read book Role of Proteases in Cellular Dysfunction written by Naranjan S. Dhalla and published by Springer Science & Business Media. This book was released on 2013-11-22 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now well known that proteases are found everywhere, in viruses and bacteria as well as in all human, animal and plant cells, and play a role in a variety of biological functions ranging from digestion, fertilization, development to senescence and death. Under physiological conditions the ability of proteases is regulated by endogenous inhibitors. However, when the activity of proteases is not regulated appropriately, disease processes can result, as seen in Alzheimer’s disease, cancer metastasis and tumor progression, inflammation and atherosclerosis. Thus it is evident that there is an absolute need for a tighter control of proteolytic activities in different cells and tissues. Aimed at graduate students and researchers with an interest in cellular proteolytic events, Role of Proteases in Cellular Dysfunctions is the second book on Proteases in this series. The book consists of three parts in specified topics based on current literatures for a better understanding for the readers with respect to their subject-wise interests. The first section of this book covers a brief idea about the neuronal disorders and the involvement of proteases such as calpains, caspases and matrix metalloproteases (MMPs). The second section covers the deadly disease cancer and its relation to ubiquitin-proteasome system, MMPs and serine proteases. The last section is about the role of proteases such as calpains, MMPs and serine protease as well as urokinase type plasminogen activator receptor (uPAR) in causing cardiovascular defects.
