Abstract
Septins are GTP-binding proteins and are involved in several cellular functions, in which they are associated to membranes, as cytokinesis, exocytosis and ciliogenesis. These proteins have been described in many organisms, and the number of septins in each organism varies from one (in some species of algae) to 13 (in humans). They are often associated as hetero-oligomers. Recently, we des…
