Mariners are small DNA mediated transposons of eukaryotes that fortuitously function in bacteria. Using bacterial genetics, it is possible to study a variety of properties of mariners, including transpositional ability, dominant-negative regulation, overexpresson inhibition, and the function of cis-acting sequences like the inverted terminal repeats. In conjunction with biochemical techniques, the structure of the transposase can be elucidated and the activity of the elements can be improved for genetic tool use. Finally, it is possible to uncover functional transposase genes directly from genomes given a suitable bacterial genetic screen.
