The Progresses of Tol2 Transposable Element of Medaka Fish
青鳉Tol2转座子研究进展

As insertional mutagens or molecular tagging, transposons have been widely used for gene isolation, cloning and function study. Most of transposons are from microorganisms and plants. Medaka Tol2 is the only natural active transposon in vertebrate until now, which was found recently and is likely a peculiar transposon system of vertebrate. The structure of Tol 2 transposable element, its transposition mechanism and application, are reviewed in this paper.
