Genome organization and nucleotide sequence of human papillomavirus type 33, which is associated with cervical cancer

Abstract

The 7,909-nucleotide sequence of human papillomavirus type 33, which is associated with cervical cancer, has been determined and used to deduce the corresponding genome arrangement. Extensive sequence homologies and other genetic features are shared with the related oncogenic virus, human papillomavirus type 16, especially in the major reading frames. A surprising difference was found in the noncoding region of human papillomavirus type 33 as, unlike all other sequenced papillomaviruses, it contains a perfect 78-base pair tandem repeat.
