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 were 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.
?Following the first volume Emerging Functions of Septins, this research topic is aimed at providing researchers with an exclusive platform to publish their latest discoveries in septin biology, in addition to discussing the concerns and advances in the field through reviews, brief research reports and opinion articles.
The topic will be open to research dealing with all aspects of septins' research including but not limited to
(I) Novel cellular and physiological functions of septins;
(II) Biochemical and structural studies on septins;
(III) Understanding the molecular mechanisms of septin dependent processes;
(IV) Development of tools and techniques for septin research.
