From: Specific distribution of overexpressed aurora B kinase in interphase normal epithelial cells
Overexpressed aurora B is incorporated into the nucleus after cell division. An NRK cell overexpressing aurora B-GFP was monitored by time-lapse microscopic imaging. Phase-contrast (a-c) and corresponding fluorescence images (a'-c') showed the dynamics of overexpressed aurora B-GFP during cytokinesis. Majority of aurora B is associated with the spindle midzone (a'-c', arrowheads) during cytokinesis. When the nuclear envelops started forming in daughter cells, a cytoplasmic fraction of overexpressed aurora B was incorporated into the nuclei (b' and c', arrows). Bar, 10 μm
