Figure 3

Schematic of the fragmentation of the Golgi complex during mitosis. A) The intact Golgi complex (GC) composed of interconnected stacks of cisternae that form a ribbon that encircles the nucleus (N), during interphase. B) Tubulation of the Golgi membranes at late G2/early prophase is observed in the absence of CtBP3/BARS. C) The Golgi complex at the beginning of mitosis, where the tubules connecting the different stacks and the cisternae undergo fission with a mechanism that depends on CtBP3/BARS. At this point, the fragments that form are dispersed into the cytoplasm.
