Abstract :
[en] PiggyBac(PB)-like elements (pble) are members of a eukaryotic DNA transposon family. This family is of interest to evolutionary genomics because pble transposases have been domesticated at least 9 times in vertebrates. The amino acid sequence of pble transposases can be split into three regions: an acidic N-terminal domain (~100 aa), a central domain (~400 aa) containing a DD[D/E] catalytic triad, and a cysteine-rich domain (CRD; ~90 aa). Two recent reports suggested that a functional CRD is required for pble transposase activity. Here we found that two CRD-deficient pble transposases, a PB variant and an isoform encoded by the domesticated PB-derived vertebrate transposase gene 5 (pgbd5) trigger transposition of the Ifp2 pble. When overexpressed in HeLa cells, these CRD-deficient transposases can insert Ifp2 elements with proper and improper transposon ends, associated with deleterious effects on cells. Finally, we found that mouse CRD-deficient transposase Pgbd5, as well as PB, do not insert pbles at random into chromosomes. Transposition events occurred more often in genic regions, in the neighbourhood of the transcription start sites and were often found in genes predominantly expressed in the human central nervous system.
