Research Abstract

In order to improve the efficiency of random insertional mutagenesis, the backbone of an NMD-suppressing poly(A)-trap technique "UPATrap" has been changed from a standard retrovirus to a DNA transposon Tol2. This modification increased the disruption rate of transcriptionally silent genes in mouse embryonic stem(ES) cells and permitted conditional inactivation of trapped genes. In addition, we solved a long-standing problem associated with the transposon vector system by incorporating a mixture of 15 differentially tagged Tol2 transposons. These developments will certainly accelerate the analyses on the nature of T lymphocytes.
