Nucleotide sequence analysis of the long terminal repeat of integrated bovine leukemia provirus DNA and of adjacent viral and host sequences.
The nucleotide sequence of the 3' long terminal repeat and adjacent viral and host sequences was determined for a bovine leukemia provirus cloned from a bovine tumor. The long terminal repeat was found to comprise 535 nucleotides and to harbor at both ends an imperfect inverted repeat of 7 bases. Promoter-like sequences (Hogness box and CAT box), an mRNA capping site, and a core enhancer-related sequence were tentatively located. No kinship was detected between this bovine leukemia proviral fragment and other retroviral long terminal repeats, including that of human T-cell leukemia virus.
