Analysis of genomic sequences of 95 papillomavirus types: uniting typing, phylogeny, and taxonomy.
Our aim was to study the phylogenetic relationships of all known papillomaviruses (PVs) and the possibility of establishing a supratype taxonomic classification based on this information. Of the many… Expand
The human papillomavirus type 16 E2 transcription factor binds with low cooperativity to two flanking sites and represses the E6 promoter through displacement of Sp1 and TFIID.
The E6 promoters of all genital human papillomaviruses have a characteristic alignment of transcription factor binding sites. Activation of the basic transcription complex at the TATA box depends… Expand

ABSTRACT The transforming proteins of the small DNA tumor viruses, simian virus 40 (SV40), adenovirus, and human papillomavirus (HPV) target a number of identical cellular regulators whose functional… Expand

The identification and taxonomy of papillomaviruses has become increasingly complex, as approximately 70 human papillomavirus (HPV) types have been described and novel HPV genomes continue to be… Expand
Transcriptional activation of human papillomavirus 16 by nuclear factor I, AP1, steroid receptors and a possibly novel transcription factor, PVF: a model for the composition of genital papillomavirus…
Human papillomavirus 16 (HPV-16), which is involved in genital carcinogenesis, contains an enhancer of transcription that is activated by cellular factors rather than by the viral E2 proteins. The… Expand
Transcription of the transforming genes of the oncogenic human papillomavirus-16 is stimulated by tumor promotors through AP1 binding sites.
The promoter P97 of human papillomavirus-16 (HPV-16) gives rise to transcripts that encode the principal transforming genes of the virus, E6 and E7. The activity of P97 is regulated by a… Expand
High Sp1/Sp3 ratios in epithelial cells during epithelial differentiation and cellular transformation correlate with the activation of the HPV-16 promoter.
Gene expression of human papillomavirus type 16 (HPV-16) and other HPV types is epithelial specific. Specificity is brought about by synergism between several different transcription factors that… Expand
YY1 represses human papillomavirus type 16 transcription by quenching AP-1 activity.
YY1 is a multifunctional transcription factor that has been shown to regulate the expression of a number of cellular and viral genes, including the human papillomavirus (HPV) oncogenes E6 and E7. In… Expand
The enhancer of human papillomavirus type 16: binding sites for the ubiquitous transcription factors oct-1, NFA, TEF-2, NF1, and AP-1 participate in epithelial cell-specific transcription.
The enhancer of human papillomavirus type 16 (HPV-16) is considered to be specific for epithelial cells, in particular for cervical carcinoma-derived cell lines. We reexamined this hypothesis with… Expand
The E6/E7 promoter of human papillomavirus type 16 is activated in the absence of E2 proteins by a sequence-aberrant Sp1 distal element.
The E6/E7 promoter of all genital human papillomaviruses is responsible for expression of the viral transforming genes. Centered 60 bp upstream of the transcription start, it contains a 20-bp segment… Expand
