MsqTc3, a Tc3-like transposon in the yellow fever mosquito Aedes aegypti.
A novel transposon, MsqTc3-Aa, has been discovered in the yellow fever mosquito, Aedes aegypti. Evidence of its past mobility is presented. There are approximately 100 copies of MsqTc3-Aa in A. aegypti, eight of which have been isolated and sequenced. All sequenced copies are more than 99% identical to their consensus, indicating recent mobilization. The MsqTc3-Aa consensus contains imperfect terminal inverted repeats (TIRs) and an open reading frame (ORF) interrupted by an intron. Sequence, structural and phylogenetic analysis showed that MsqTc3-Aa is a distant relative of Tc3, an active transposon in Caenorhabditis elegans. These results may provide useful information for the current effort to control mosquito-borne diseases using genetic approaches.
