From: Whole genome sequencing in Drosophila virilis identifies Polyphemus, a recently activated Tc1-like transposon with a possible role in hybrid dysgenesis

Figure 2

Polyphemus is a cut and paste transposon belonging to the Tc1 family. (A) Overall structure of Polyphemus with 235-bp inverted repeats indicated by black arrows. Asterisks indicate putative alternate translation start sites. Position of the DDE motif that catalyzes the transposition reaction is indicated. (B) Alignment of amino acids that contain the DDE motif from closely related members of the Tc1 family: the founding Tc1 as well as the S element (from D. melanogaster) and Paris (from D. virilis). (C) Phylogeny of the Tc1/mariner family. Polyphemus, Paris, and S element form a clade within the Tc1 group.
