TREP, the TRansposable Elements Platform

Superfamily CACTA                   DTC

Full classification: DNA-transposon, TIR, CACTA

CACTA elements are Class 2 transposons.

They are well characterised in plants. Abundant in higher plants.. The terminal repeats usually end in CACTA (5' end) and TAGTG (3' end).
Upon insertion, they create a 3 bp Target site duplication (TSD).

Structure of CACTA 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

ORF2: ORF2 protein
Function: Protein of unknown function
Protein motifs:

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