The functional significance of sequence variation within the upstream regulatory region (URR) of six human papillomavirus type 16 (HPV16) cervical cancer isolates from Australia was investigated. Specific changes in transcription factor binding sites leading to increased promoter activity may explain the transforming ability of some episomal HPV16 isolates.
