- Abstract:
The genome of the house fly, Musca domestica, contains an active
transposable element system, called Hermes. Using PCR and inverse PCR we
amplified and sequenced overlapping segments of several Hermes elements
and from these data we have constructed a 2749 bp consensus Hermes DNA
sequence. Hermes termini are composed of 17 bp imperfect inverted repeats
that are almost identical to the inverted terminal repeats of the hobo
element of Drosophila melanogaster. Full length Hermes elements contain a
single long ORF capable of encoding a protein of 612 amino acids which is
55% identical to the amino acid sequence of the hobo transposase.
Comparison of the ends of the Hermes and hobo elements to those of the Ac
element of Zea mays, and the Tam3 element of
Antirrhinum majus, as well as
several other plant and insect elements, revealed a conserved terminal
sequence motif. Thus Hermes is clearly a member of the hobo, Ac and Tam3
(hAT) transposable element family, other members of which include the Tag1
element from Arabidopsis thaliana and the Bg element from Zea mays. The
evolution of this class of transposable elements and the potential utility
of Hermes as a genetic tool in M. domestica and related species are
discussed.
