WebSeptins are GTP-binding proteins that are evolutionarily and structurally related to the RAS oncogenes. Septin expression levels are altered in many cancers and new advances point to how abnormal septin expression may contribute to the progression of cancer. In contrast to the RAS GTPases, which are frequently mutated and actively promote tumorigenesis, … WebMar 1, 2001 · Recent work suggests novel functions for septins in vesicle trafficking, oncogenesis and compartmentalization of the plasma membrane. Given the ability of the septins to bind GTP and phosphatidylinositol 4,5-bisphosphate in a mutually exclusive manner, these proteins might be crucial elements for the spatial and/or temporal control …
WebMay 24, 2011 · Septins are a family of proteins highly conserved in eukaryotes that have been under intense scrutiny lately because they appear to comprise a novel component of the cytoskeleton. As such, septins play important roles in many cellular processes by providing rigidity to the cell membrane, serving as scaffolds to recruit proteins to specific … WebSeptins Are in Small, Oligomeric Complexes in Cytosol. To determine how and where septins transition from monomers to filaments, we observed septins in the cytosol of three different fungal organisms: Schizosaccharomyces pombe, Saccharomyces cerevisiae, and Ashbya gossypii. These three systems have distinct cell mor-
