E5.LRM4 cooperates with a juxtamembrane PDGF β receptor mutant. BaF3 cells expressing the βαβ chimera (black bars), the wild-type PDGF β receptor (gray bars), or PR-K499D (white bars) were infected with retroviruses expressing no insert (vec), the wild-type E5 protein, or the indicated E5 mutant. Viable cells were counted and recorded as described in the legend of Fig. 2. Statistical significance of the results of the PR-K499D tests compared to the E5/PR-K499D combination is indicated by one asterisk (P ≤ 0.05) or two asterisks (P ≤ 0.01).
