  TITLE     Further evidence for the protein coding potential of the mouse
            mammary tumor virus long terminal repeat: Nucleotide sequence of an
            endogenous proviral long terminal repeat

COMMENT     [1] feels that the unidentified reading frame, denoted as pLTR,
            codes for a nonstructural protein functional in the life cycle of
            the MMTV. The endogenous MMTV CH3 virus long terminal repeat is not
            identical with the exogenous viral long terminal repeat. There is a
            6.6% divergence between the two sequences. The nature of the
            sequence changes within the open reading frame are highly
            non-random with respect to the amino acid codons.
