中文摘要：

从家蝇转录组数据库中筛选到一条精氨酸激酶同源序列，将其命名为家蝇精氨酸激酶（Muscadomestica arginine kinase，简称：MdAK）．通过RT—PCR克隆得到MdAKcDNA序列，长2007bp，编码356个氨基酸残基，编码蛋白的分子质量为40．0ku．利用RNAi技术敲低家蝇幼虫精氨酸激酶的表达后，其生长发育受到影响，死亡率明显升高．认为精氨酸激酶可以作为害虫生物防治的潜在靶点．

英文摘要：

An arginine kinase homologue, named MdAK, was found in the Musca domestica transcrip- tomic database. A 2 007 bp-length cDNA was cloned by RT-PCR and it encoded a polypeptide with 356 a- mino acid residues weighted 40.0 ku. Silencing MdAK with RNAi led to developmental retardation and in- creased mortality of larva. The results suggested that MdAK could be taken as a potential target spot of pest control.
