Orchestrating vesicle transport, ESCRTs and kinase surveillance during abscission.

During the final stage of cell division, the future daughter cells are physically separated through abscission. This process requires coordination of many molecular machines, including endocytic and secretory vesicle trafficking proteins as well as ESCRT (endosomal sorting complex required for transport) proteins, that mediate a complex series of events to culminate in the final separation of daughter cells. Abscission is coordinated with other cellular processes (for example, nuclear pore reassembly) through mitotic kinases such as Aurora B and Polo-like kinase 1, which act as master regulators to ensure proper progression of abscission.
