RESUMO

This work studied the design, construction, and cleavage analysis of zinc finger nucleases (ZFNs) that could cut the specific sequences within microphthalmia - associate transcription factor (mitfa) of zebra fish. The target site and ZFPs were selected and designed with zinc finger tools, while the ZFPs were synthesized using DNAWorks and two-step PCR. The ZFNs were constructed, expressed, purified, and analyzed in vitro. As expected, the designed ZFNs could create a double-stand break (DSB) at the target site in vitro. The DNAWorks, two-step PCR, and an optimized process of protein expression were firstly induced in the construction of ZFNs successfully, which was an effective and simplified protocol. These results could be useful for further application of ZFNs - mediated gene targeting.
