Figure 1.
Construction and validation of EGFP–FLAG tagged HDACs 1–11. (Left) HDAC 1–11 tagged with EGFP (green)–FLAG (red) at their C terminus. Boundaries of the deacetylase (yellow), MEF2 binding (brown), nuclear localization signal NLS (blue) and nuclear export signal NES (orange) regions are indicated. (Center) Deacetylase activity of HDACs isolated from CEM T cells measured using the Fluor-de-Lys assay (n=3, AFU±s.d.), as compared to EGFP–FLAG controls. (Right) Localization of EGFP–FLAG tagged HDACs in CEM T-cell lines using anti-GFP antibody (green); DNA is indicated by DAPI (blue); × 63 oil immersion lens; scale bar, 5 μm.
