TREP, the TRansposable Elements Platform

Superfamily hAT                   DTA

Full classification: DNA-transposon, TIR, hAT

hAT elements are Class 2 transposons.

They are widespread in eukaryotes but not very abundant. Upon insertion, they create a 8 bp Target site duplication (TSD).

Structure of hAT elements

Sequence domains

TIR5: Terminal inverted repeat
Function: Contains motifs that are recognized and bound by the transposase. Essential for transposition.
Protein motifs:

TASE: Transposase
Function: Required for excision and insertion
Protein motifs: DDE

TIR3: Terminal inverted repeat
Function: Contains motifs that are recognized and bound by the transposase. Essential for transposition.
Protein motifs:
