Scale bar -1 µm.(F) Stills from time-lapse sequence of representative Hela cells expressing mNeon-Green Aurora B and Cell Mask to label cell membrane, exiting mitosis, showing the dynamic re-localization of Aurora B from DNA to the overlapping microtubules and cleavage furrow with control siRNA treatment (arrows top). With knock-down of RACGAP1, Aurora B still re-localises from the DNA to the microtubules and furrow in the midzone in early anaphase (arrows bottom), but the microtubule localization is lost at later stages (asterisk bottom).

Note, failure in actin accumulation in RACGAP1 depleted cell, asterisk. Scale bar - 10 µm(F) Quantification of actin intensity across the perimeter of the cells based on distance from DNA, with 5 and 6 being closest to DNA and 1 and 10 furthest away, as in cartoon (B). Graph shows decrease in actin intensity closer to the DNA in siControl (n=26), siRACGAP1 (n=37) and Control DMSO treated cells (n=38 cells), seen by levels lower than 1 (dotted red line), while this decrease is absent in ZM447439 treated cells (n=42 cells).
