ABSTRACT The human papillomavirus (HPV) life cycle is tightly linked to differentiation of the squamous epithelia that it infects. Capsid proteins, and hence mature virions, are produced in the outermost layer of differentiated cells. As late gene transcripts are produced in the lower layers, posttranscriptional mechanisms likely prevent capsid protein production in less differentiated cells. For HPV type 16 (HPV-16), a 79-nucleotide (nt) negative regulatory element (NRE) inhibits gene expression in basal epithelial cells. To identify key NRE sequences, we carried out transient transfection in basal epithelial cells with reporter constructs containing the HPV-16 late 3′ untranslated region with deletions and mutations of the NRE. Reporter gene expression was increased over 40-fold by deletion of the entire element, 10-fold by deletion of the 5′ portion of the NRE that contains four weak consensus 5′ splice sites, and only 3-fold by deletion of the 3′ GU-rich region. Both portions of the element appear to be necessary for full repression. Inactivating mutations in the 5′ splice sites in the 5′ NRE partially alleviated repression in the context of the 79-nt NRE but caused full derepression when assayed in a construct with the 3′ NRE deleted. All four contribute to the inhibitory effect, though the second splice site is most inhibitory. Sm proteins, U1A and U1 snRNA, but not U1 70K, could be affinity purified with the wild-type NRE but not with the NRE containing mutations in the 5′ splice sites, indicating that a U1 snRNP-like complex forms upon the element.
