Figure 7. UL97 directs FoxM1 phosphorylation on Thr600.
(A) Saos-2 cells were transfected with expression plasmids for T7-tagged FoxM1 together with either an empty vector (EV), HA-tagged wild-type UL97 (97), the indicated allele of UL97, or cyclin E1/CDK2. Lysates harvested 48 hr after transfection were analyzed by western blot with the indicated antibodies. (B) NHDFs were transfected with the CMV promoter-driven T7-tagged FoxM1. At 18 hr post-transfection the transfected NHDFs were serum-starved. After 48 hr cells were infected with HCMV at an MOI of 3. At 2 hr post-infection infected cells were treated with 10 μM maribavir (MBV) or DMSO as a vehicle. Whole cell lysates were prepared at 48 hr post-infection and analyzed by western blot with the indicated antibodies.
