TREP, the TRansposable Elements Platform

Superfamily Bel-Pao                   RLB

Full classification: Retrotransposon, LTR, Bel-Pao

Bel-Pao elements are Class 1 transposons.

They are not so well characterized, found in animals. Upon insertion, they create a 5 bp Target site duplication (TSD).
