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 ... WebSep 1, 2012 · Budding Yeast Septins: Molecular Organization, Self-Assembly and Lipid Interactions. In budding yeast septin’s essential function in cytokinesis involves their role as a scaffold for the recruitment of both structural and signaling proteins in the septation process. 12 Septins also form a barrier that prevents the diffusion of proteins between …
