Book Description
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.

Book Description
Over the last decade, major advancements in our understanding of the ubiquitin-proteasome system (UPS) have occurred. This book focuses on recent trends in the UPS. The UPS is possibly the most complex of all intracellular pathways as close to 7% of all genes in the human genome make up part of the UPS. This complex system serves as an essential role in intracellular protein degradation, and because of its critical function, improper functioning of the UPS is associated with nearly all know diseases, including cancer, cardiovascular disease, and neurological diseases. The proteolytic component of the UPS is the proteasome, a multicatalytic complex found in the nucleus and cytoplasm. Another form of the proteasome, the immunoproteasome, is less abundant than the constitutive proteasome, but is important in immune response and degradation of oxidized proteins, and recent research suggests that it may be important in longevity. The articles in this book discuss recent findings which indicate that mutations in proteins involved with the UPS are associated with genetic diseases such as familial dilated cardiomyopathy, Nakajo syndrome, and spinal muscular atrophy (X-linked). Some chapters also discuss recent results which suggest that the UPS is heavily regulated by post-translational modifications such as phosphorylation, acetylation, and methylation. The UPS is also heavily regulated by ubiquitination itself. This book contains a research article using PubMed bibliometric data to present current research trends in the UPS. Articles are written so that no one tissue is emphasized to allow readers from any discipline to benefit from this information.

Book Description
In recent years, powered by evolving technologies and experimental design, studies have better illuminated the regulating role of proteolytic enzymes across human development and pathologies. Proteolytic Signaling in Health and Disease provides an in-depth discussion of fundamental physiological and developmental processes regulated by proteases, from protein turnover and autophagy to antigen processing and presentation and major histocompatibility complex (MHC) molecules. Moving on from basic biology, international chapter authors examine a range of pathological conditions associated with proteolysis, including inflammation, wound healing, and cancer. Later chapters discuss the newly discovered network of connected events among proteases (and their inhibitors), the so-called 'protease web', and how best to study it. This book also empowers new research with up-to-date analytical methods and step-by-step protocols for studying proteolytic signaling events. - Examines biological events triggered by proteolytic enzyme activity across human development and pathologies - Discusses the role of proteolytic signaling in inflammation, wound healing, and cancer, among other disease types - Features methods and protocols supporting further study of proteolytic signaling events - Includes chapter contributions from international leaders in the field

Book Description
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.
