The key role of ubiquitination and sumoylation in signaling and cancer by Hui-Kuan Lin,Wenyi Wei Pdf

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.

Ubiquitin and Ubiquitin-Relative SUMO in DNA Damage Response by Kristijan Ramadan,Ivan Dikic Pdf

DNA damage response (DDR) is a term that includes a variety of highly sophisticated mechanisms that cells have evolved in safeguarding the genome from the deleterious consequences of DNA damage. It is estimated that every single cell receives tens of thousands of DNA lesions per day. Failure of DDR to properly respond to DNA damage leads to stem cell dysfunction, accelerated ageing, various degenerative diseases or cancer. The sole function of DDR is to recognize diverse DNA lesions, signal their presence, activate cell cycle arrest and finally recruit specific DNA repair proteins to fix the DNA damage and thus prevent genomic instability. DDR is composed of hundreds of spatiotemporally regulated and interconnected proteins, which are able to promptly respond to various DNA lesions. So it is not surprising that mutations in genes encoding various DDR proteins cause embryonic lethality, malignancies, neurodegenerative diseases and premature ageing. The importance of DDR for cell survival and genome stability is unquestionable, but how the sophisticated network of hundreds of different DDR proteins is spatiotemporally coordinated is far from being understood. In the last ten years ubiquitin (ubiquitination) and the ubiquitin-relative SUMO (sumoylation) have emerged as essential posttranslational modifications that regulate DDR. Beside a plethora of ubiqutin and sumo E1-activating enzymes, E2-conjugating enzymes, E3-ligases and ubiquitin/sumo proteases involved in ubiquitination and sumoylation, the complexity of ubiqutin and sumo systems is additionally increased by the fact that both ubiquitin and sumo can form a variety of different chains on substrates which govern the substrate fate, such as its interaction with other proteins, changing its enzymatic activity or promoting substrate degradation. The importance of ubiquitin/SUMO systems in the orchestration of DDR is best illustrated in patients with mutations in E3-ubiquitin ligases BRCA1 or RNF168. BRCA1 is essential for proper function of DDR and its mutations lead to triple-negative breast and ovarian cancers. RNF168 is an E3 ubiquitin ligase, which creates the ubiquitin docking platform for recruitment of different DNA damage signalling and repair proteins at sites of DNA lesion, and its mutations cause RIDDLE syndrome characterized by radiosensitivity, immunodeficiency and learning disability. In addition, recently discovered the ubiquitin receptor protein SPRTN is part of the DNA replication machinery and its mutations cause early-onset hepatocellular carcinoma and premature ageing in humans. Despite more than 700 different enzymes directly involved in ubiquitination and sumoylation processes only few of them are known to play a role in DDR. Therefore, we feel that the role of ubiquitin and the ubiquitin-related SUMO in DDR is far from being understood, and that this is the emerging field that will hugely expand in the next decade due to the rapid development of a new generation of technologies, which will allow us a more robust and precise analyses of human genome, transcriptome and proteome. In this Research Topic we provide a comprehensive overview of our current understanding of ubiquitin and SUMO pathways in all aspects of DDR, from DNA replication to different DNA repair pathways, and demonstrate how alterations in these pathways cause genomic instability that is linked to degenerative diseases, cancer and pathological ageing.

SUMO Regulation of Cellular Processes by Van G. Wilson Pdf

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.

SUMO Regulation of Cellular Processes by Victor Willson Pdf

Over a decade ago, a small cellular protein of 12 kDa, with 18% homology to the well-known ubiquitin protein, was co-discovered and termed Small Ubiquitin-like Modifier, or SUMO. Sumoylation is a post-translational modification that utilizes SUMO as the modifier group covalently attached to target substrates. This state-of-the art review on the sumoylation system deals with protein modification as it pertains to regulation of diverse cellular functions. Each chapter has been written by a leading researcher and covers the role of sumoylation in fundamental biochemical activities (transcription, RNA processing, chromatin remodelling, DNA repair, nucleocytoplasmic transport, ion channel regulation, and metabolic pathways). The text also examines the part sumoylation plays in critical cellular processes such as mitosis, meiosis, differentiation, senescence, and apoptosis. Lastly, the emerging role of sumoylation in specific diseases, including cancer and diabetes as well as neurodegenerative ones, is explored with an emphasis on defining molecular mechanisms that may provide new targets for treatment or prevention. While SUMO was discovered more than 10 years ago, this is still a relatively young field, and much remains to be discovered about the biochemical and biological properties of this modification system. In just the last few years, it has become clear that sumoylation modifies hundreds of cellular proteins, and there has been increased appreciation for the breadth of cellular functions that are impacted by this post-translational modification.

Protein Metabolism and Homeostasis in Aging by Nektarios Tavernarakis Pdf

Aging is loosely defined as the accumulation of changes in an organism over time. At the cellular level such changes are distinct and multidimensional: DNA replication ceases, cells stop dividing, they become senescent and eventually die. DNA metabolism and chromosomal maintenance, together with protein metabolism are critical in the aging process. The focus of this book is on the role of protein metabolism and homeostasis in aging. An overview is provided of the current knowledge in the area, including protein synthesis, accuracy and repair, post-translational modifications, degradation and turnover, and how they define and influence aging. The chapters mainly focus on well-characterised factors and pathways, but new areas are also presented, where associations with aging are just being elucidated by current experimental data. Protein turnover, the balance between protein synthesis and protein degradation are carefully maintained in healthy cells. Chapters 1 and 2 illustrate that aging cells are characterised by alterations in the rate, level and accuracy of protein synthesis compared to young ones, and that mRNA translation, essential for cell growth and survival, is controlled at multiple levels. The theory that growth and somatic maintenance are believed to be antagonistic processes is described in Chapter 3: inhibition of protein synthesis results in decreased rates of growth and development, but also confers an extension of lifespan, as shown for example by the effects of dietary restriction in various models organisms.

Ubiquitin Proteasome System by Matthew Summers Pdf

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.

SUMO Protocols by Helle Ulrich Pdf

Post-translational protein modifications by members of the ubiquitin family are widely recognized as important regulatory control systems for a variety of biological pathways. Their influence on eukaryotic cellular metabolism is comparable to that of other modifi- tions such as phosphorylation, acetylation and methylation. The small ubiquitin-related modifier SUMO uses a conjugation and de-conjugation system closely related to that of ubiquitin itself; yet, the functions of the SUMO system are highly diverse and largely independent of the ubiquitin system. SUMO modification controls the activity of tr- scription factors and can influence protein stability, but it also contributes to nucleo-cy- plasmic transport, chromosome segregation and DNA damage repair. As a consequence, the SUMO system pervades virtually all areas of basic molecular and cell biology, and scientists from different backgrounds, including medical researchers, are likely to enco- ter SUMO in the course of their studies. This volume, SUMO Protocols, therefore aims at presenting a collection of methods relevant to SUMO research in order to make these tools available to biochemists, molecular and cell biologists as well as research-oriented clinicians not yet familiar with the system. In contrast to the ubiquitin system, which has been the subject of several reviews and methods collections, no practical compendium entirely devoted to SUMO has been p- lished.
