Book Description
Regulation of protein structure and function by post-translational modification is a key mechanism in cellular homeostasis. Among known modifications the small protein ubiquitin is unique in the breadth of functions it directs. Regulation of protein ubiquitylation is the function of more than 600 ligases, and ~100 deubiquitinases. Dysregulated ubiquitylation is involved in infection, inflammation, neurodegeneration, metabolic syndromes and cancer. Therapeutic intervention in these conditions benefits from characterization of substrate-specific ligases and deubiquitinases. Substrate specificity is documented among deubiquitinases, but lags behind knowledge of ligases. In the interest of characterizing specificity of cysteine protease deubiquitinases we have developed chemical methods for site-specific ubiquitylation and electrophile incorporation. We began by developing a ubiquitin-derived electrophile through installation of a C-terminal selenocysteine residue, and orthogonal oxidative conversion to dehydroalanine. Upon validation of the electrophile we expanded our substrate scope to a ubiquitylated peptide, with which we captured the deubiquitinase USP15. In order to access ubiquitylated lysine residues in protein regions inaccessible by native chemical ligation we undertook the synthesis of two selenazolidine amino acids for amber suppression. While conducting amber suppression selections we concurrently pursued semi-synthesis of p53, in order to introduce a C-terminal ubiquitin electrophile. Purification of the semi-synthetic protein proved materially intensive, prompting development of cleavable affinity handles for ligation product purification. A strategy for incorporation at glycine and incorporation at glutamine were developed. A glycine-derived biotin handle proved amenable to reduction by Zn, which furnishes a native glycine, and aromatic thiols, which formed novel site-specific conjugates at the previously modified glycine. Incorporation of a pendant flag tag at glutamine enabled immunoprecipitation followed by traceless tag removal with Zn.

Book Description
The genetic, molecular, and cellular mechanisms of neural development are essential for understanding evolution and disorders of neural systems. Recent advances in genetic, molecular, and cell biological methods have generated a massive increase in new information, but there is a paucity of comprehensive and up-to-date syntheses, references, and historical perspectives on this important subject. The Comprehensive Developmental Neuroscience series is designed to fill this gap, offering the most thorough coverage of this field on the market today and addressing all aspects of how the nervous system and its components develop. Particular attention is paid to the effects of abnormal development and on new psychiatric/neurological treatments being developed based on our increased understanding of developmental mechanisms. Each volume in the series consists of review style articles that average 15-20pp and feature numerous illustrations and full references. Volume 2 offers 56 high level articles devoted mainly to Formation of Axons and Dendrites, Migration, Synaptogenesis, Developmental Sequences in the Maturation of Intrinsic and Synapse Driven Patterns. Series offers 144 articles for 2904 full color pages addressing ways in which the nervous system and its components develop Features leading experts in various subfields as Section Editors and article Authors All articles peer reviewed by Section Editors to ensure accuracy, thoroughness, and scholarship Volume 2 sections include coverage of mechanisms which regulate: the formation of axons and dendrites, cell migration, synapse formation and maintenance during development, and neural activity, from cell-intrinsic maturation to early correlated patterns of activity

Book Description
Using a multidisciplinary approach, this book describes the biochemical mechanisms associated with dysregulation of proteases and the resulting pathophysiological consequences. It highlights the role and regulation of different types of proteases as well as their synthetic and endogenous inhibitors. The role of proteases was initially thought to be limited to general metabolic digestion. However, we now know that the role of protein breakdown is much more complex, and proteases have multiple functions: they are coupled to turnover and can affect protein composition, function and synthesis. In addition to eliminating abnormal proteins, breakdown has many modulatory functions, including activating and inactivating enzymes, modulating membrane function, altering receptor channel properties, affecting transcription and cell cycles and forming active peptides. The ubiquity of proteases in nature makes them an important target for drug development. This in-depth, comprehensive is a valuable resource for researchers involved in identifying new targets for drug development. With its multidisciplinary scope, it bridges the gap between fundamental and translational research in the biomedical and pharmaceutical industries, making it thought-provoking reading for scientists in the field.

Book Description
Ubiquitination is a biological process mediated by ubiquitin itself, the E1 ubiquitin-activating enzyme, E2 ubiquitin-conjugating enzyme, E3 ubiquitin ligase, and deubiquitinating enzyme, respectively. Currently, these multiple biological steps are revealed to participate in various life phenomena, such as cell proliferation, regulation of cell surface proteins expression, and mitochondrial function, which are profoundly related to human health and diseases. Although clinical applications targeting ubiquitination are still limited compared to those directed toward kinase systems such as tyrosine kinases, multiple enzymatic consequences should be future therapeutic implications. This Special Issue of IJMS entitled “Ubiquitination in Health and Disease” successfully published15 distinguished manuscripts, with a total of 66 international authors and. This book provides the latest and most useful information for researchers and scientists in this field.

Book Description
Type IV secretion systems (T4SSs) are highly versatile membrane-associated transporter machines used by Gram-negative and Gram-positive bacteria to deliver substrate molecules to a large variety of target cells. This volume summarizes our current knowledge of the large variety and structural diversity of T4SSs in pathogenic Escherichia, Agrobacterium, Legionella, Coxiella, Bartonella, Helicobacter, Enterococcus and other species. Divided into 13 chapters contributed by leading experts, it presents findings that significantly enhance our understanding of how various pathogens manipulate host cell functions to trigger bacterial uptake, promote intracellular growth, suppress defense mechanisms and of how bacteria spread antibiotic resistances, thus facilitating bacterial colonization and disease development. The book is an invaluable source of information for researchers and clinicians.
