Abstract: hATm is a separate group of hAT DNA transposons. Significant identity between hATm and hAT transposases appears after PSI BLAST iterations. hATm transposons exist in genomes of different animals, including segmented worms (Helobdella robusta, leech), flatworms (Schmidtea mediterranea, freshwater planarian), insects (Aedes aegyptus, mosquito), and tunicate (Ciona savignyi sea squirt). All identified hATm transposons are characterized by 8-bp target site duplications and conserved termini (5'-TAGGgtGgyccnnA). The planarian hAT-7_SM, hAT-8_SM and hAT-10_SM transposons also belong to the hATm group. Their putative classification as hAT transposons was not supported by significant similarity (BLAST and PSI-BLAST) to known hAT transposase proteins. hATm-3_HR is a young family of haTm transposons identified in the leech genome. The consensus sequence was built based on multiple alignment of 5 copies that are ~2% divergent from the consensus. TIRs are 15-bp long. This transposon is target site specific: hATm-3_HR copies are usually inserted into (TA)n.
