  TITLE     Long terminal repeats of endogenous mouse mammary tumour virus
            contain a long open reading frame which extends into adjacent
            sequences

COMMENT     Six bases at the end of each LTR form inverted repeats, and the
            first six bases of each flanking sequence form direct repeats. This
            endogenous long terminal repeat is not identical to that of the
            exogenous MMTV long terminal repeat.
               There is an open reading frame within both long terminal repeat
            regions. The open reading frame of the left LTR extends into the
            adjacent mouse sequence and the open reading frame of the right LTR
            starts at the viral env gene/LTR junction. The corresponding RNA
            for each hypothetical protein has not yet been isolated.
