Casein Kinase II Motif-Dependent Phosphorylation of Human Papillomavirus E7 Protein Promotes p130 Degradation and S-Phase Induction in Differentiated Human Keratinocytes

Abstract excerpt

The E7 proteins of human papillomaviruses (HPVs) promote S-phase reentry in differentiated keratinocytes of the squamous epithelia to support viral DNA amplification. In this study, we showed that nuclear p130 was present in the differentiated strata of several native squamous epithelia susceptible to HPV infection. In contrast, p130 was below the level of detection in HPV-infected patient specimens. In submerged...
