Cytokinesis: An Anillin-RhoGEF Module Sets the Stage for Septin Double Ring Assembly.

Summary In many eukaryotes septin filaments form an hourglass-like structure at the division site that rearranges into a double ring at cytokinesis. A new study elucidates how an anillin–RhoGEF complex guides the assembly of the septin double ring in budding yeast.
