NINJA_I (DF0001675)

LTR retrotransposon NINJA, internal sequence.


This is the internal sequence of LTR retrotransposon NINJA, its LTR is NINJA_LTR. It contains two open reading frames (ORFs), and the pol region is divided between two ORFs in contrast to the organization of other retrotransposons. An alignment analysis of the reverse transcriptase sequences suggested that the NINJA element is the first Drosophila retrotransposon belonging to the PAO subgroup [1].
