Septins are GTPases involved in cytokinesis. The septins localize to the site of cleavage and act as a structural scaffold that recruits different components involved in diverse processes at specific stages during the cell cycle. Septins are also involved in cell morphogenesis, chitin deposition, cell cycle regulation, cell compartmentalization and spore wall formation (By similarity). Component of the septin complex. Expressed in late sporogonial stages. Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. Septin GTPase family.
