Molecular cloning and nucleotide sequence of deer papillomavirus

Abstract

The genome of deer papillomavirus (DPV) isolated from American white-tailed deer was cloned into pBR322, and the entire nucleotide sequence of 8,374 base pairs was determined. The overall genetic organization of the DPV genome was similar to that of other papillomaviruses. All significant open reading frames were located on one strand, and the locations of putative promoters and polyadenylation signals were similar to those identified in the closely related bovine papillomavirus type 1 (BPV-1) genome. The DPV genome was approximately colinear with BPV-1 except for a noncoding region separating the early and late regions. The regions of highest nucleotide sequence homology between DPV and BPV-1 were found in the E1 open reading frame coding for BPV-1 DNA replication function and in the L1 open reading frame, which encodes the major capsid protein of BPV-1.
