Figure 5. HEK 293T cells were transfected with 1 µg of UNG2–2HA expression vector together with the indicated expression vectors.

Forty-eight hours after transfection nuclear and cytoplasmic fractions were prepared. The composition of these fractions was characterized by immunoblotting with HA-, DDB1-,α tubulin- or anti-Histone H3-specific antibodies (A). 293T cells were transfected with UNG2–2HA expression vector, together with empty vector, or expression vector for wild type HIV1 FLAG–Vpr (3 µg). MG132 (12.5 µM) or DMSO (vehicle control) were added 24 hours after transfection. 16 hours later nuclear and cytoplasmic fractions were prepared and characterized by immunoblotting with anti-HA, anti-FLAG, anti-α tubulin (cytoplasmic fraction control) and anti-Histone H3 (nuclear fraction control) antibodies (B).
