Book Description
ATPases Associated with diverse cellular Activities (AAA+) comprise a superfamily of proteins that are defined by the presence of the AAA+ domain containing canonical Walker A and B motifs required for ATP binding and hydrolysis. Members of this superfamily act on other proteins, DNA, RNA, or multicomponent complexes to affect their conformation or their assembly. There have been substantial advances in understanding the structure and mechanism of function of a large number of AAA+ proteins. In this Research Topic, review articles and original research papers discuss new aspects as well as provide a detailed overview of several AAA+ proteins, namely: ClpXP, Lon, ClpB, Hsp104, p97, AAA+ proteins of the proteasome, Rubisco activases, Torsin, Pontin, and Reptin.

Book Description
This volume gives an overview of pro tea some-mediated protein degradation and the regulatory role of the ubiquitin system in cellular proteolysis. The first chapter describes the molecular evolution of the proteasome and its associated activators, i. e. , the 20S core, the base and the lid of the 19S cap, and the 11 S regulator. The ensuing chapter gives an overview of the structure and assembly of the 20S proteasome and the regulation of the archaeal proteasome by PAN. The third contribution summarizes our knowledge on the eukaryotic 26S proteasome and its regulation by the 19S regu lator, followed by a chapter devoted to the llS regulator, which elucidates the structural basis for the 11 S-mediated activation of the 20S proteasome. The fifth chapter reviews in detail the role of the proteasome in the immune response. The subsequent chapter of the natural substrates of the gives a comprehensive description proteasome and their recognition by the enzymes of the ubiqui tination machinery. The penultimate chapter rounds up the in formation on intracellular distribution of proteasomes in yeast and mammalian cells, while the last contribution highlights proteasome inhibitors, tools which proved to be very valuable for dissecting the cellular roles of the proteasome and which might turn out to be of pharmacological importance.

Book Description
Pathophysiological Aspects of Proteases in Cancer provides a comprehensive overview of the multifaceted field of proteases in the cellular environment and focuses on the recently elucidated functions of complex proteolytic systems in physiology and pathophysiology. The book both gives insights on the general aspects of the role of proteases in cancer, their role as diagnostics and prognostics biomarkers, their impact on chemoresistance, and the future cutting-edge technologies like cocktail therapies and Cyber Knife technology. Given the breadth and depth of information covered in the respective contributions, the book will be immensely useful for researchers in oncology and working to identify targets for drug development.Multidisciplinary in scope, the book bridges the gap between fundamental and translational research, with applications in the biomedical and pharmaceutical industry, making it a thought-provoking read for basic and applied scientists engaged in biomedical research. - Gives insight into the spectrum of proteases, protease inhibitors, and protease interactors involved at the cellular and molecular level in cancer development - Gives a comprehensive overview of the role of proteases in modulating cellular metabolism and chemoresistance to better understand how proteases play in early to the end point in cancer development and metastasis - Provides a multidisciplinary approach demonstrating the biochemical and signal transduction mechanisms associated with dysregulation of proteases, leading to the manifestation of various diseases - Highlights the roles and regulation of different types of proteases, as well as their synthetic and endogenous inhibitors - Bridges the gap between fundamental and translational research, with applications in the biomedical and pharmaceutical industry

Book Description
DNA repair is fundamental to all cell types to maintain genomic stability. A collection of cutting-edge reviews, DNA Repair - On the pathways to fixing DNA damage and errors covers major aspects of the DNA repair processes in a large variety of organisms, emphasizing foremost developments, questions to be solved and new directions in this rapidly evolving area of modern biology. Written by researchers at the vanguard of the DNA repair field, the chapters highlight the importance of the DNA repair mechanisms and their linkage to DNA replication, cell-cycle progression and DNA recombination. Major topics include: base excision repair, nucleotide excision repair, mismatch repair, double-strand break repair, with focus on specific inhibitors and key players of DNA repair such as nucleases, ubiquitin-proteasome enzymes, poly ADP-ribose polymerase and factors relevant for DNA repair in mitochondria and embryonic stem cells. This book is a journey into the cosmos of DNA repair and its frontiers.

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.

Book Description
Ubiquitination and Sumoylation are two important posttranslational modifications that play pivotal roles in a variety of biological functions. Although Ubiquitination is traditionally viewed as a critical mark targeting proteins for proteasome-dependent degradation, recent studies reveal that it also plays nonproteolytic functions. In contrast, Sumoylation is long thought not to target proteins for degradation, accumulating evidence suggests that it can serve a priming effect prerequisite for ubiquitination, thereby inducing protein ubiquitination and degradation. Thus, there is an important cross-talk between sumoylation and ubiquitination in determining protein fate. Deregulation in these two marks may cause aberrant activity of proteins and in turn contributes to cancer development. In this Research Topic, we accept review articles, perspectives, research articles covering any one or both of these two posttranslational modifications in regulating diverse signal transduction pathways and providing the novel insights in unraveling the puzzle as to how they may regulate cancer progression and metastasis.
