Disassembly of F-actin with latrunculin A has no significant effects on TMS stability and behavior. Cells expressing mito-dsRed and Mgm101GFP were treated with 300 µM latrunculin A for 20 min to cause disassembly of F-actin (not depicted). Cells were analyzed subsequently using time-lapse fluorescence microscopy at 1-min intervals, and the image represents a 0.2-µm section.
