Transib is a superfamily of interspersed repeats DNA transposons.
[1] An intact element including terminal inverted repeats (TIR) was found in 2008 in the Helicoverpa zea genome.
The differences lie in the domain organization of the core transcriptase; TransibSU is also notable for having RAG2-like proteins.[3]: fig.
An active transposon with RAG1/2-like genes ("ProtoRAG"; PDB: 6B40) has been discovered in B. belcheri (Chinese lancelet).
The TIRs are structurally similar to Recombination signal sequences (RSS).
