FIG. 8.
Overexpression of tankyrase 2 in the nucleus releases TRF1, but not TRF2, from telomeres. (A) Schematic diagram of the tankyrase 2 expression construct. M, Myc epitope tag; N, SV40 NLS. (B) Indirect immunofluorescence of HelaI.2.11 cells transiently transfected with MN-tankyrase 2, formaldehyde fixed, and stained with anti-myc antibody (green) (B and C) and anti-TRF1 antibody 415 (red) (B′) or anti-TRF2 antibody (red) (C′). DAPI staining of DNA is shown in blue. Scale bar, 5 μm.
