Title:
Autonomous Chapaev transposons from the hydra genome.

Abstract:
Chapaev-3_HM is a young family of autonomous Chapaev DNA transposons that were active in the hydra genome less than a few million years ago (they are 2% divergent from their consensus sequence). The consensus sequence was obtained based on a multiple alignment of 6 copies; it codes for a 975-aa Chapaev transposase (ten exons). Chapaev-3_HM is characterized by 4-bp target site duplications, 11-bp terminal inverted repeats, and 22-bp subterminal inverted repeats (separated by 17- and 7-bp regions from the 5' and 3' TIRs, respectively). The Chapaev-3_HM TPase forms a distinctive group of Chapaev TPases (including Chapaev-4_HM, Chapaev-6_HM, Chapaev-7_HM, Chapaev-8_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).
