DNA2-2_DR (DF0003022)

Non-autonomous DNA transposon from zebrafish

Description

The genome harbors several thousand copies of DNA2-2_DR that are ~95% identical to their consensus sequence (~100 copies were transposed as a portion of the hAT-N18 element). DNA2-2_DR elements are characterized by TA target site duplications and 14-bp terminal inverted repeats. Additionally, the 3' terminus contains a 63-bp palindrome (pos. 718-780). DNA2-2_DR elements are also characterized by a high target-site specificity. They are inserted preferentially into the cawTAwtg target-sites (TA -is a target site duplication). Classification of DNA2-2_DR is not certain yet, although it is expected to be a member of the Mariner/Tc1 superfamily. It has some subterminal similarity to the Tag1-like hAT-2_HM element.
