incubation of Kat1 and a 197 bp duplex corresponding to TIR-R with 48 bp from the transposon and 149 bp flanking DNA. First Kat1 cleaves the transposon end, generating a free 3' hydroxyl. Joining of one 3'-OH to the target generates a nicked plasmid or single end-joining (SEJ) product. If two 3'-OHs join the target at complementary positions on opposite strands, the plasmid is linearized generating a double end-joining (DEJ) product. Kat1 displays target joining, generating both SEJ- and DEJ-products |

incubation of Kat1 with a 40 bp duplex representing imperfect inverted repeat TIR-R and including 30 bp from the transposon end and 10 bp from the flanking DNA. Kat1 cleaves the upper strand primarily at GTATA*C and to less extent at GTAT*AC. In the reaction using 3' end-labeling of the upper strand a product of 23 nts is observed. The products formed from the lower strand are hairpin-capped. No substrate: a 40 bp duplex representing imperfect inverted repeat TIR-L |

formation of a Hermes transposase-DNA complex. Bipartite DNA recognition at hAT transposon ends and Hermes-DNA interactions within the transpososome. No protein-DNA interactions involving bp 12-16 of the TIR. The avidity provided by multiple sites of interaction allows a transposase to locate its transposon ends amidst a sea of chromosomal DNA, mechanism, overview. The enzyme possesses a RNaseH-like catalytic domain interrupted by a large [.alpha]-helical insertion domain, and an N-terminal intertwined dimerization domain. Together, these domains catalyze the chemical steps of DNA nicking, hairpin formation, and DNA strand transfer that comprise hAT transposition |

H2K A/J muscle cells properly express full-length human DYSF following SB-mediated gene transfer. A duplicate of Spc5-12 (2xSpc5-12) regulatory sequence proves to be the most efficient in driving transgene expression in H2K A/J myoblasts. Corrected H2K A/J myoblasts can efficiently be transplanted into Scid/BLA/J mouse muscle |

the sleeping beauty transposon DNA contains the gene to be inserted into the target DNA flanked by inverted terminal repeats (IR-DRleft and IR-DRright). Each inverted terminal repeat contains two, inner and outer, direct repeats (DRs). The DRs represent binding sites for the transposase enzyme. Sleeping beauty, SB, appears to be the most random in preferences for integration sites, requiring only a TA dinucleotide basepair. Binding mechanism, detailed overview |

for examination of the transposition activity of recombinant Tgf2 TPase, microinjection is performed in blunt snout bream embryos at 1-2 cell stage. When donor plasmid pTgf2-EF1alpha-EGFP is co-injected with recombinant Tgf2 TPase protein, 74% of the embryos show almost ubiquitous and uniform expression of EGFP, while 31% control embryos by injected donor plasmid show only mosaic expression of EGFP. Four EGFP-positive blunt snout bream are sampled from the group coinjected with donor plasmid with recombinant Tgf2 TPase. An 8-bp direct repeat of target DNA at the integration site, the signature of hAT family transposons, is created adjacent to both ends of Tgf2 at the integration sites in all fish, indicating the recombinant Tgf2 TPase insertions occur by transposition |

Tgf2 is an autonomously active vertebrate transposon that is efficient at gene-transfer in teleost fish. The N-terminal zinc finger domain of Tgf2 transposase contributes to DNA binding and to transposition activity. Proposed model for Tgf2 transposition, overview |
