This fluorescence micrograph of a Ptk2 cell shows the localization of tubulin (red) and a member of the dynactin-protein-complex, p22 (green), during cytokinesis. Dynactin is a macromolecular complex that is required for activating cytoplasmic dynein-mediated vesicular transport. This figure shows that the dynactin complex is prominently localized within the midbody of the dividing cells (yellow), thus suggesting that dynein/dynactin complexes may have a novel role during cytokinesis.
