TREP, the TRansposable Elements Platform

Superfamily P                   DTP

Full classification: DNA-transposon, TIR, P

P elements are Class 2 transposons.

They are found in animals and plants. Well characterised in animals (Drosophila). Upon insertion, they create a 8 bp Target site duplication (TSD).

Structure of P 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:
