title: The interaction between p53 and papillomaviruses.
abstract: The p53 tumour suppressor is one of the host's principal defences against viral replication and subsequent cell transformation. The human papillomaviruses have evolved an elaborate strategy whereby the viral E6 proteins directly target p53 for ubiquitin mediated degradation and thus overcome the inhibitory effects of p53. However, a more detailed picture of the HPV*b1p53 interaction is now emerging in which there is a complex interplay between both positive and negative effectors of these interactions. This demonstrates the existence of a finely balanced virus*b1host relationship which, on rare occasion, fails and initiates the processes that ultimately lead to malignancy.
