TREP, the TRansposable Elements Platform

Superfamily R2                   RIR

Full classification: Retrotransposon, non-LTR (SINE), R2

R2 elements are Class 1 transposons.

They are found in animals. Upon insertion, they create a variable bp Target site duplication (TSD).

Structure of R2 elements

Sequence domains

RT: Reverse transcriptase
Function: Reverse transcription of mRNA to DNA, core motif is relatively variable (FY)(IAMV)DD
Protein motifs: YVDD

EN: Endonucleasease
Function:
Protein motifs:

polyA: Poly-A tail
Function: Result of reverse transcription of mRNA. Sometimes, it is not a poly-A (weird stuff)
Protein motifs:
