Abstract
Synthetic oligonucleotides complementary to putative retroviral primer-binding sites were used as hybridization probes to detect novel retroviruslike sequences. An 8.1-kilobase element with structural features of a retroviral provirus was isolated from a human genomic library by this approach. Nucleotide sequence analysis of its 600-base-pair long terminal repeats revealed characteristic motifs known as regulatory signals for RNA polymerase II transcription: CCAAT, TATA, and ATTAAA. In addition, a putative pol gene displays apparent homologies to conserved regions of retroviral reverse transcriptase. The 5' long terminal repeat is flanked at its 3' end by a putative primer-binding site for reverse transcription with homology to tRNA(Pro). This element is therefore termed HuRRS-P (human retrovirus-related sequence-proline). There are 20 to 40 copies of HuRRS-P homologous sequences in DNAs of human and simian origin.
