Title:
hAT6 - a novel group of hAT DNA transposons characterized by 6-bp target site duplications.

Abstract:
hAT6-2_NV is a young family of hAT DNA transposons and it belongs to a novel group of hAT transposons, called hAT6, generating 6-bp target site duplications upon their insertions into chromosomal DNA. The hAT6 transposase is distantly similar to the standard hAT transposase; identified hAT6 transposase sequences form a distinctive phylogenetic cluster and they are also present in different species, e.g. sea urchin. hAT6-2_NV is flanked by 13-bp TIRs (2 mismatches) and encodes a 746-aa transposase (6 exons). The genome contains only a few copies; therefore the TPase-encoding region in the consensus can be corrupted by mutations. The genome contains more than 1000 copies of non-autonomous transposons (e.g. the hAT6-N1_NV, hAT6-N2_NV, hAT6-N3_NV, and haT6-N4_NV families) transposed in the past by TPases expressed by some autonomous transposons similar to hAT6-2_NV.
