TREP, the TRansposable Elements Platform

Superfamily Gypsy                   RLG

Full classification: Retrotransposon, LTR, Gypsy

Gypsy elements are Class 1 transposons.

They are extremely well characterized and widespread in animals, plants, fungi and some other eukaryotes. The terminal repeats usually end in TG (5' end) and CA (3' end).
Upon insertion, they create a 5 bp Target site duplication (TSD).
