  HPVs are small, double-stranded DNA viruses that infect mucosal and cutaneous epithelial tissues.Since HPVs do not encode a viral DNA polymerase, these viruses are completely dependent on the host cell machinery for DNA replication except an origin-binding protein and a replicative DNA helicase.The functions of two viral proteins, E6 and E7, from high risk type HPVs, are reflected in many of the cellular proteins with which they interact.Among a variety of cellular targets, the effects of E6 and E7 on p53 and pRb as well as on many other cellular proteins have been extensively investigated in the past.
