GFP-Fzy dynamics in a bubR1-KEN1 mutant neuroblast. bubR1-KEN1 mutant Drosophila larval neuroblast labeled with GFP-Fzy (green; top left) and RFP-BubR1-KEN1 (red; top right). Merged images are shown in the bottom left panel. The GFP-Fzy channel corresponds to Fig. 3D. Images were acquired by confocal spinning disk microscopy. Frames were taken every 20 s for 13.20 min. The video is shown at 8 frames/s.
