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-1_HR is a young family of hATm autonomous DNA transposons identified in the leech genome. TIRs are 14-bp long (one mismatch). The TPases is encoded by a single ORF that contains a stop-codon.
