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.

Most proteins undergo post-translational modifications altering physical and chemical properties, folding, conformation distribution, stability, activity and function. Ubiquitin and SUMOs are related small proteins that are members of the large ubiquitin superfamily of post-translational modifiers. Written by highly respected leaders in their fields under the expert guidance of the editor, this volume covers the principles of ubiquitination and SUMOylation, presents detailed reviews of current and emerging concepts and highlights new advances in all areas of SUMOylation and ubiquitination. Topics of note include: the ubiquitin superfamily, the ubiquitin toolbox, onco viral exploitation of the SUMO system, small molecule modulators of desumoylation, mass spectrometry, global proteomic profiling of SUMO and ubiquitin, biotin-based approaches, genetic screening, SUMOylation networks in humans, targets for ubiquitin ligases, regulation of p53, protein homeostasis, miRNAs, DNA replication, DNA damage response, telomere biology, intracellular trafficking, regulation of angiogenesis, brain ischemia, autophagy, assembly and activity, antiviral defense, HIV infection, amyloid and amyloid-like proteins, plant immunity. This comprehensive and up-to-date book is the definitive reference volume on all aspects of SUMOylation and ubiquitination and is an essential acquisition for anyone involved in this area of biology.

A panel of leading academic and pharmaceutical investigators takes stock of the remarkable work that has been accomplished to date with proteasome inhibitors in cancer, and examines emerging therapeutic possibilities. The topics range from a discussion of the chemistry and cell biology of the proteasome and the rationale for proteasome inhibitors in cancer to a review of current clinical trials underway. The discussion of rationales for testing proteasome inhibitors in cancer models covers the role of the proteasome in NF-kB activation, the combining of conventional chemotherapy and radiation with proteasome inhibition, notably PS-341, new proteasome methods of inhibiting viral maturation, and the role of protesome inhibition in the treatment of AIDS. The authors also document the development of bortezomib (VelcadeTM) in Phase I clinical trials and in a multicentered Phase II clinical trials in patients with relapsed and refractory myeloma.

“This volume explores numerous techniques used to study the ubiquitin proteasome system. The chapters in this book are organized into five parts and cover topics such as determining the mechanisms of action for E2s, E3s, and DUB enzymes; the latest advances to study the formation of poly-ubiquitin chains as well as their linkage types; the binding partners of proteins in the UPS; methods for structure determination by x-ray crystallography, cryo electron microscopy and SAXS; screening assays to select for degrons or modulators of E3s and DUBs; proteomics approaches in the ubiquitin field and methods to study 26S proteasome function. Written in the highly successful Methods in Molecular Biology series format, 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. Thorough and authoritative, The Ubiquitin Proteasome System: Methods and Protocols is a valuable resource for both experienced and novice scientists who are interested in expanding their knowledge in this field.

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.

This is the second edition of a very well received book that details how the sumoylation system functions and how it modulates numerous cellular activities. SUMO is a post-translational modifier in the ubiquitin super-family that has gained recognition over the last twenty years as an essential and prevalent regulatory molecule. Individual chapters explore the biochemistry, molecular biology, and cell biology of the sumoylation system and its substrate proteins. The book is divided into three themed parts: Molecular Functions (I), Cell Growth Regulation (II), and Diseases (III). Parts I and II focus on the contribution of sumoylation to cellular activities in both the nuclear and cytoplasmic compartments. The nuclear activities covered include nucleic acid metabolism (both RNA and DNA), chromosome structure and replication, and nucleocytoplasmic transport. Cytoplasmic processes presented include regulation of membrane ion channels, general metabolism, and apoptotic signalling. Topics in Part III include the role of sumoylation in developmental abnormalities (craniofacial and cardiovascular), diabetes, neurodegenerative diseases, cancer, and infections with viruses and bacteria. Each of the corresponding chapter authors is an active researcher who has made significant contributions to understanding sumoylation. This second edition provides updates and revisions to most of the original chapters plus adds six new chapters to address important developing areas of sumoylation research. This volume is intended for a scientific audience from undergraduates to independent researchers. The content will serve as both a solid introduction for the novice reader and an in depth treatment for the advanced scholar.
