A member of the Tc1 family of transposable elements has been identifie
d in the Central and South American mosquito Anopheles albimanus. The
full-length Quetzal element is 1680 base pairs (bp) in length, possess
es 236 bp inverted terminal repeats (ITRs), and has a single open read
ing frame (ORF) with the potential of encoding a 341-amino-acid (aa) p
rotein that is similar to the transposases of other members of the Tc1
family, particularly elements described from three different Drosophi
la species. The approximately 10-12 copies per genome of Quetzal are f
ound in the euchromatin of all three chromosomes of A. albimanus. One
full-length clone, Que27, appears capable of encoding a complete trans
posase and may represent a functional copy of this element.
