Figure 2. Human piggyBac-like transposable elements have intact inverted terminal repeat sequences similar to the T. ni piggyBac transposon.
(A) Chromosome ideogram representing the distribution of annotated piggyBac-like elements in the human genome (version hg19). (B) Multiple sequence alignment of the piggybac inverted terminal repeat (ITR) sequence with the consensus ITR sequences of the MER75 and MER85 families of piggyBac-like elements. (C) Chromosome ideogram representing the distribution of piggyBac-like elements annotated in the human genome (version hg19) with TTAA target site duplication as well as ITR sequences aligning with the consensus (intact ITRs).
