from Scott B. Vande Pol writing in Small DNA Tumour Viruses:
Papillomavirus E6 oncoproteins are small zinc-binding proteins with a bewildering array of biological activities, including modulation of apoptosis, cellular transcription, host cell differentiation, growth factor dependence, DNA damage responses, and cell cycle progression. How can such a tiny protein do so much? This review examines insights from studies of oncogenic human papillomavirus E6 and bovine papillomavirus E6 to illuminate the mechanism by which E6 proteins interact with cellular binding partners. The origins of E6 and the history of its investigation are presented with the discovery of the major interaction partners that mediate E6 effects on DNA damage responses, cellular transcription, and modulation of keratinocyte differentiation.
