WebArf6 knockdown was without effect on cytokinesis, but when both Rab 11 and Arf6 were knocked-down, we found the furrow rapidly regressed and the cells were unable to form a stable midbody. We suggest that Rab 11 and Arf6 function synergistically in the switch from furrowing to abscission, as well as in the terminal stage of abscission.

WebCytokinesis A is a myosin-dependent active furrowing and is the sole means of division under circumstances where cells cannot adhere to a surface, such as in suspension or on a hydrophobic surface.
