Calcium And Calmodulin Function In The Cell Nucleus

de Neus Agell e Oriol Bachs

118,59€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This book is about the role of calcium and calmodulin in the cell nucleus. Calcium, which is an important second messenger of signal transduction pathways, can also operate in the cell nucleus. Different calcium binding proteins, which are the targets of cellular calcium, have been identified in the nucleus of many different cell types. Prominent among these calcium binding proteins is calmodulin, which appears to be involved in the regulation of major nuclear functions such as gene expression and DNA replication.

Intracellular Signal Transduction: The Jak-Stat Pathway

de Ailsa G. Harpur e Andrew F. Wilks

118,59€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This book is the first one written about the JAK/STAT pathway. The JAK (Janus Kinase) Protein tyrosine kinases are novel phosphotransferases absolutely required for cellular signalling downstream of non-catalytic cytokine receptors (amongst others). These molecules are components in pathways utilising the STAT (Signal Transducers and Activators of Transcription) transcription factors. The basic components of the JAK/STAT pathway are covered in detail, and the centre piece of the book is a guided tour of the pathway itself. An interesting addition to the book is the chapter on the use of Drosophila melanogaster as a genetic system to probe the pathway at the whole organism level. The book is targeted to researchers who have an interest in intracellular signalling.

Organellar Proton-Atpases

de Nathan Nelson

59,61€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 THE WORLD OF PROTON PUMPS Nathan Nelson uite frequently an observer looks at a life phenomenon and asks ~himself why nature took this route out of several other available mec anisms. In order to understand this challenge he may first try to reconstruct the evolution of the process taking into account the main driving forces that were assumed to exist during the last 3. 5 billion years on earth. Now we know that the electrochemical gradient of protons is the universal high-energy intermediate produced and uti lized by every living cell in nature. This high energy intermediate is an expression of different concentrations of active protons in the two faces of biological membranes. Why then did nature elect to utilize a pre dominantly electrochemical gradient of protons and no other ion? The answer to this question may lie in the environment in which the first living creatures evolved. Some of them may have been challenged by an acidic environment that lowered their internal pH (by a proton leak through their membranes) to lethal levels. To counteract these inci dents proton pumps evolved. Two independent systems were devel oped. One was a proton pump coupled to energetically downhill vectorial electron transport across membranes and the second was an ATP-dependent proton pump. Both of them pump protons outward from the cells generating an electrochemical gradient of protons.

Pre-Mrna Processing

59,61€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 he past fifteen years have seen tremendous growth in our understanding of T the many post-transcriptional processing steps involved in producing func tional eukaryotic mRNA from primary gene transcripts (pre-mRNA). New processing reactions, such as splicing and RNA editing, have been discovered and detailed biochemical and genetic studies continue to yield important new insights into the reaction mechanisms and molecular interactions involved. It is now apparent that regulation of RNA processing plays a significant role in the control of gene expression and development. An increased understanding of RNA processing mechanisms has also proved to be of considerable clinical importance in the pathology of inherited disease and viral infection. This volume seeks to review the rapid progress being made in the study of how mRNA precursors are processed into mRNA and to convey the broad scope of the RNA field and its relevance to other areas of cell biology and medicine. Since one of the major themes of RNA processing is the recognition of specific RNA sequences and structures by protein factors, we begin with reviews of RNA-protein interactions. In chapter 1 David Lilley presents an overview of RNA structure and illustrates how the structural features of RNA molecules are exploited for specific recognition by protein, while in chapter 2 Maurice Swanson discusses the structure and function of the large family of hnRNP proteins that bind to pre-mRNA. The next four chapters focus on pre-mRNA splicing.

 Joseph E. Alouf "The empirical basis of objective science has thus nothing ''abso lute'' about it. Science does not rest upon solid bedrock. The bold structure of its theories rises, as it were, above swamp. It is like a building erected on piles. The piles are driven down from above into the swamp, but not down to any natural or ''given'' base; and if we stop driving the piles deeper, it is not because we have reached firm ground. We simply stop when we are satisfied that the piles are firm enough to carry the structure, at least for the time being. " -Karl Popper (The Logic of Scientific Discovery) hen I was invited to write this introductory chapter I was hon W ored and pleased to have the opportunity to briefly highlight some important issues relevant to structural aspects of bacterial protein tox ins. The present book attempts for the first time to provide into one volume a series of chapters prepared by invited experts on the struc ture of these fascinating macromolecules.

Meaning Of Nucleocytoplasmic Transport

de Paul S. Agutter e Philip L. Taylor

59,61€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The means by which proteins and RNAs are exchanged between cytoplasm and nucleus have interested cell biologists for many years, and the field has seen a number of exciting recent advances. Much has been learned about the intricate architecture of the nuclear pore-complex, the mechanisms by which transport substrates are sorted, and the supply of energy for exchange processes. This book attempts a general review of the growing body of knowledge. However, the authors challenge the presumptions implicit in some interpretations of the evidence, re-examining the concept of "transport" within cells, and suggesting that lessons learned from nucleocytoplasmic transport studies can elucidate wider aspects of cell biology.

Statistics Of Natural Selection On Animal Populations

de Brian F. Manly

59,61€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 In the concluding chapter of his famous book on the theory of evolution by natural selection, Charles Darwin (1859) remarked that: When the views entertained in this volume on the origin of species, or when analogous views are generally admitted, we can dimly foresee that there will be a considerable revolution in natural history. This proved, of course, to be completely correct. At present there is a great divergence of opinion about the general importance of natural selection in the evolutionary process. Nevertheless, biologists are, on the whole, united in their acceptance of the potential power of selection in changing populations. Given this situation, it is not surprising to find that many attempts to detect the effects of natural selection have been made since the time of Darwin. This area of study has been called ecological genetics. It involves the collection of data of various kinds and, in many cases, the development of special methods for analysing these data. This book is a summary of methods for data analysis, concentrating on those that are applicable to animal populations, particularly wild populations.
