Title:
Autonomous Chapaev transposons from the hydra genome.

Abstract:
Chapaev-8_HM is a young family of autonomous Chapaev DNA transposons that were active in the hydra genome less than a few million years ago (copies are ~2% divergent from their consensus sequence). The consensus sequence was obtained based on a multiple alignment of 15 incomplete copies; it codes for a 841-aa Chapaev transposase (ten exons). The consensus sequence is incomplete (its 3'-terminal portion in unknown). The Chapaev-8_HM TPase forms a distinctive group of Chapaev TPases (including Chapaev-3_HM, Chapaev-4_HM, Chapaev-6_HM, Chapaev-7_HM), whose 240-300-aa N-terminal portion composed of the Chapa zinc and RING fingers is similar to the N-terminal portion of RAG1 (pos. ~100-380). For instance, the N-terminal portion of the Chapaev-8_HM transposase (pos. 4-245) is 27% identical to the RAG1 N-terminal portion (E value <1e-14).
