A pulse of Arp2/3 recruitment prior to exocytosis is not associated with Mroh1.
The presence of RFP-ArpC4 (left) on the vesicle does not parallel the behaviour of either Mroh1-GFP (right) nor, by implication, WASH. The time with respect to vesicle exocytosis (in seconds) is shown. Scale bar = 10µm.
