Jockey2 (DF0001661)

JOCKEY2 is a non-LTR retrotransposon


JOCKEY2 belongs to the JOCKEY clad of non-LTR retrotransposons. Its copies have 3' poly(A) tail and they are flanked by ~10-bp direct repeats generated upon integration into genome. JOCKEY2 forms a separate family of retrotransposons that were active in the ancestral form of the D. melanogaster genome ~5 Myr ago. The 5'-portion of JOCKEY2 cannot be reconstructed completely from the current sequence data. The consensus sequence contains several deletion (~200-bp at position 250, ~900-bp at position 307, and ~370-bp at position 1365). The JOCKEY2 ORF1 and ORF2, which encode the Jockey-like gag and pol proteins, are corrupted by mutations. ORF2 is defined by positions 879-3221.
