TRANSPOSASE AND METHOD OF GENE MODIFICATION

摘要

A transposase encoded by the Tol2 element; a polynucleotide encoding the same; a method of modifying the gene structure of a cell (preferably a vertebrate cell) by using the above protein; a method of modifying the function of a cell by modifying the gene structure thereof; and a cell having been modified in function by these methods. Also the structure of a cis element necessary in gene transfer is clarified and presented.
