High-risk HPV E6 and E7 oncoprotein expression is important for malignant transformation of cervical cancer cells. In particular, the E7 protein of high-risk HPV binds to pRB family members (pRB, p107, and p130) for degradation. p107 and p130 pocket proteins are members of mammalian DREAM complexes, which are temporally regulated during cell cycle. E7 targets p130 for HPV16 to promote the host cell to exit from quiescence (G 0 ) state and enter S phase. However, p130 is also degraded in HPV48 even though HPV48 E7 does not binding directly to the pocket protein. Therefore we explored the mechanisms responsible for the activities of HPV16 E7 and HPV48 E7 on disruption of p130/DREAM complex.The experiments were done with a p130 mutant that is defective in binding the E7 LXCXE motif (p130mE7) and another mutant that cannot be phosphorylated by CDK (p130PM22). In addition, a double mutant (p130PM22/mE7) was constructed. The p130 mutants and the wild-type p130 were expressed in HPV-transformed cell lines and FACS analysis was done. Subsequently, the T98G glioblastoma cell line was used to ectopically express both HPV16 and 48 with the p130 mutants.The p130mE7 and p130mE7/PM22 mutants prevented the binding of 16E7 in CaSki cells, whereas p130PM22 and p130mE7/PM22 mutants prevented the binding of 48E7 in T98G cells.HPV16 E7 targets p130 predominantly through direct interactions via the LXCXE motif whereby HPV48 E7 disrupts p130/DREAM via CDK2 phosphorylation.
