Survivin is a determining factor for mitotic localization of the chromosome passenger complex. Survivin is a determining factor for mitotic localization of the chromosome passenger complex. (A) U2OS cells were transfected with the indicated plasmids. Puromycin was added to enrich for transfected cells. Lysates were analysed by western blotting. (B,C) Cells were transfected with the indicated short interfering RNA (siRNA) plasmids combined with the indicated VSV‐tagged constructs. (B) After release from a thymidine block, cells were treated with Taxol and collected for fluorescence‐activated cell sorting (FACS) analysis 18 h later. Mitotic percentages were determined by MPM‐2 staining. (C) Cells were collected for FACS analysis 60 h after transfection. (D,E) Cells grown on coverslips were transfected with mock or inner centromere protein (INCENP)/Survivin siRNA plasmids, VSV–Survivin–INCENP47–920‐sil and H2B–GFP (green fluorescent protein). Immunostainings were carried out with the indicated antibodies. DNA (H2B–GFP) is depicted in blue. (F) Cells grown on coverslips were transfected with the indicated plasmids and H2B–GFP. Cells were stained with anti‐Aurora‐B, and the percentage of H2B–GFP‐positive prometaphase cells in which Aurora‐B localized on the centromeres was scored. The number of cells counted per condition is indicated. (G) Time‐lapse images of a representative cell transfected with INCENP siRNA plasmid, Survivin–INCENP47–920‐sil–GFP and H2B–diHcRed. Differential interference contrast (DIC), GFP and diHcRed signals are shown. (H) Time‐lapse imaging of cells transfected with mock (upper panel) or Survivin siRNA plasmid (lower panel), INCENP1–47‐GFP and H2B–diHcRed. Scale bars, 5 μm. Gerben Vader et al.
