Human papillomavirus genomes replicate extrachromosomally in infected tissues and derived keratinocyte cells. The cell line CIN12 9E was established from a cervical CIN1 lesion, contains replicating HPV31 genomes, and is widely used as a model to study the HPV life cycle. Here, we clone and sequence the HPV31 9E genome.
