Böcker i SpringerBriefs in Biochemistry and Molecular Biology-serien

This SpringerBrief explores unconventional functions of eight different transcription factors and concludes with a discussion of their biological significance and impact, including effects on processes within the cell nucleaus during development and in adult organisms. Chapter One details unconventional functions of the transcription factors GAGA, HP1, Rb, STAT, ATF-2 and NF-kB. Surprisingly, all of these transcription factors can be found in association with heterochromatin as well as euchromatin, and in some cases unconventional functions have been demonstrated for these heterochromatin-associated factors. Chapter Two focuses on the unconventional functions of STAT and HP1 and discusses their roles in the promotion of longevity, and in protection from cancer and DNA damage. Chapter Three explores the biological significance of the findings presented in the first two chapters and considers how global changes in the epigenome brought about by factors such as STAT and HP1 might affect processes within the cell nucleus during development and in adult organisms. This succinct yet thorough SpringerBrief is essential for researchers studying epigenetics, and to instructors of the subject. It should also appeal to people interested in the control of gene transcription and other processes in the cell nucleus, and to those interested in development.

There is now compelling evidence that the complexity of higher organisms correlates with the relative amount of non-coding RNA rather than the number of protein-coding genes. Previously dismissed as "e;junk DNA"e;, it is the non-coding regions of the genome that are responsible for regulation, facilitating complex temporal and spatial gene expression through the combinatorial effect of numerous mechanisms and interactions working together to fine-tune gene expression. The major regions involved in regulation of a particular gene are the 5' and 3' untranslated regions and introns. In addition, pervasive transcription of complex genomes produces a variety of non-coding transcripts that interact with these regions and contribute to regulation. This book discusses recent insights into the regulatory roles of the untranslated gene regions and non-coding RNAs in the control of complex gene expression, as well as the implications of this in terms of organism complexity and evolution.

Gamma-Glutamyl Transpeptidases (y-GTs) are members of the N-terminal nucleophile hydrolase superfamily, enzymes that cleave the y-glutamyl amide bond of glutathione to liberate cysteinylglycine. The released y-glutamyl group can be transferred to water (hydrolysis) or to amino acids or short peptides (transpeptidation). y-GT plays a key role in the gamma glutamyl cycle by regulating the cellular levels of the antioxidant glutathione, hence it is a critical enzyme in maintaining cellular redox homeostasis.y-GT is upregulated during inflammation and in several human tumors, and it is involved in many physiological disorders related to oxidative stress, such as Parkinson's disease and diabetes. Furthermore, this enzyme is used as a marker of liver disease and cancer. This book covers current knowledge about the structure-function relationship of y-GTs and gives information about applications of y-GTs in different fields ranging from clinical biochemistry to biotechnology and biomedicine.

The essential question that fractal dimensions attempt to answer is about the scales in Nature. For a system as non-idealistic and complex as a protein, studying scale-invariance becomes particularly important.Fractal Symmetry of Protein Exterior investigates the diverse facets of the various scales at which we describe protein biophysical and biochemical phenomena. Although these ideas are entirely mathematical, mathematical expositions have been avoided, unless the use of some expressions becomes absolutely obligatory. A first chapter introduce into fractal dimensions, protein exteriors and to methods to study the roughness of surfaces. The main topics covered in the following chapters include: protein-protein interaction interfaces; protein surface-roughness and local shape as well as adhesion on protein and other rough biomolecular surfaces.

The essential question that fractal dimensions attempt to answer is about the scales in Nature. For a system as non-idealistic and complex as a protein, studying scale-invariance becomes particularly important.Fractal Symmetry of Protein Interior investigates the diverse facets of the various scales at which we describe protein biophysical and biochemical phenomena. Following a thorough introduction to fractal dimensions, fractal-dimension-based approaches, that have been employed to study protein interior biophysical properties, are described. The focus is on the question "e;which scales are scale-invariant?"e; Investigations related to scaling of biophysical and biochemical behaviors may one day help us to formulate a fundamental theory about protein biophysics; which, in turn, may help us to understand fundamental principles of proteins.

This book explores key applications of phage biotechnology and reviews recent advances in phage display technologies. Recent studies combine the genomic flexibility of phages with phage display systems in order to generate modified phages for targeted delivery.

This Brief provides a concise review of chaperonopathies, i.e., diseases in which molecular chaperones play an etiologic-pathogenic role. Introductory chapters deal with the chaperoning system and chaperoning teams and networks, HSP-chaperone subpopulations, the locations and functions of chaperones, and chaperone genes in humans.

This book intends to be an easy and concise introduction to the field of nuclear magnetic resonance or NMR, which has revolutionized life sciences in the last twenty years.
