"The authors represent most of the key figures and the work and the book as a whole is an essential reference for the newcomer or specialist in this area and for any student of eukaryotic cell structure and function. This is an important and wonderful reference." –Microbiology Today, May 2009 Septins are an evolutionarily conserved group of GTP-binding and filament-forming proteins that were originally discovered in yeast. Once the preserve of a small band of yeast biologists, the field has grown rapidly in the past few years and now encompasses the whole of animal and fungal biology. Furthermore, septins are nowadays recognized to be involved in a variety of disease processes from neoplasia to neurodegenerative conditions. This book comprehensively examines the septin gene family and their proteins, providing those new to this research area with a detailed and wide ranging introduction to septin biology. It starts with a unique historical perspective on the development of the field, from its beginnings in the screen for cell division mutants by the Nobel Laureate Lee Hartwell. The evolution of the septin gene family then forms a basis for consideration of the biochemistry and functions of septins in yeast and other model organisms including C. elegans and Drosophila. A major part of the book considers the diversity of septins in mammals, their functions and properties as well as their involvement in normal and abnormal cellular states, followed by a speculative overview from the editors of the key questions in septin research and of where the field may be headed. In addition, several appendices summarise important information for those in, or just entering, the field, e.g. nomenclature and septin and septin-like sequences. This book is an essential source of reference material for researchers in septin biology, cell biology, genetics and medicine, in particular pathology, including areas of neurobiology, oncology, infectious disease and developmental biology.
Together with the microfilament, microtubule and intermediate-filament networks, septins constitute an integral part of the eukaryotic cytoskeleton. Historically identified as proteins critical for septum formation in the budding yeast Saccharomyces cerevisiae, septin family GTPases are expressed and participate in the process of cytokinesis in most eukaryotes except higher plants. More than a dozen septin genes in mammals, together with various splice variants displaying tissue-specific expression patterns and flexible hetero-polymeric higher-order assembly achieve an unfathomable complexity superior to the other cytoskeletal components. Even though the initial studies in the septin field was restricted to their evolutionarily conserved role in cell division, strong expression of septins in the non-dividing cells of the brain generated great interest in understanding their role in neuronal morphogenesis and other aspects of cellular function. On one hand, recent developments indicate complex non-canonical roles for septins in diverse processes ranging from neuronal development to immune response and calcium signaling. On the other hand several lines of data including those from knockout models question the universal role for septins in animal cell cytokinesis. Mammalian hematopoietic cells seem to proliferate and efficiently undergo cytokinesis in the absence of pivotal septin proteins in a context-dependent manner. The lack of septin-dependence of hematopoiesis also opens the possibility of safely targeting septin-dependent cytokinesis for solid-tumor therapy. Thus the septin field is perfectly poised with novel roles for septins being discovered and the basic understanding on septin assembly and its canonical functions constantly revisited. The objective of this research topic was to provide an exclusive platform for discussing these rapid advances in the septin field. With a mixture of reviews and research articles encompassing diverse areas of septin research, ranging from the humble yeast model to human cancer, this ebook will be an interesting reading material for both experts as well as new comers to the septin field.
