Abstract:
This is a consensus sequence of a family of non-autonomous Helitron transposons transposed in the Drosophila yakuba genome a few million years ago (numerous copies are less than 2% divergent from the consensus sequence). DNAREP1_DYak is a deletion derivative of the autonomous Helitron-1_DYak. These transposons are usually inserted in the ttw|TTT target sites without the target site duplications (the insertion site is marked by "|"). Different families of Helitrons constitute >3% of the D. yakuba genome. After a view unsuccessful attempts [1-2], it is a final classification of DNAREP1_DM as a Helitron transposon. While DNAREP1 elements have lost its mobility in D. melanogaster, they have been mobile in the D. yakuba genome till last ~1-2 million years.
