There are three folders contained herein. Human-papilloma contains 50 human papilloma DNA sequences in standard EMBL format. Of these sequences, 46 are complete genomes, while 4 contain only the E6 region of the virion. This fact is reflected in the locus and filename of these 4 sequences by an appended "E6" to the name. Animal-papilloma contains 11 animal papilloma DNA sequences in standard EMBL format 9 of which are complete genomes. The other 2 are partial as indicated by the appended "p" on the file names. Cellular-proteins contains EMBL-format nucleotide sequences of 36 cellular factors which interact directly or indirectly with papilloma virus proteins. As a result of these interactions the regulation of other cell proteins may be altered. This process may be involved in tumorogenesis.
