Growing evidence indicates that membrane traffic plays a crucial role during the late post-furrowing steps of cytokinesis in animal cells. Indeed, both endocytosis and exocytosis contribute to stabilizing the intercellular bridge that connects the daughter cells and to the final abscission in diverse organisms. The need for several intracellular transport routes probably reflects the complex events that occur during the late cytokinesis steps such as local remodelling of the plasma membrane composition, removal of components required for earlier steps of cytokinesis and membrane sealing that leads to daughter cell separation. In this mini-review, I will focus on recent evidence showing that endocytic pathways, such as the Rab35-regulated recycling pathway, contribute to the establishment of a PtdIns(4,5)P2 lipid domain at the intercellular bridge which is involved in the localization of cytoskeletal elements essential for the late steps of cytokinesis. Possible cross-talk between Rab35 and other endocytic pathways involved in cytokinesis are also discussed.
