FIG. 6.

The J domain but not the pRb-binding domain of BKV TAg is required for the induction of serum-independent growth. For each cell line, 2 × 10⁴ cells were plated in medium containing 0.1% serum. Cells from duplicate wells were counted every other day. Values shown are averages from three independent experiments. Symbols: ○, BKT; ▪, E109K; •, PTP; ▴, H42Q.
