Despite their being genetically functionless, recent findings suggest that Alu elements may hae a broad eolutionary impact by affecting gene structures, protein sequences, splicing motifs and expression patterns.

尽管Alu在遗传学上是无功能的，但是在近些年的发现中推测Alus元素可能通过影响基因结构，蛋白质序列/剪接motif和表达方式从而有广泛的进化影响力。

So thealternative splicing of tra-1 mRNA maybe happened.The whole procedure initiates a novelty technique in the study of Mermithidae. What is more, it has settled a rigid foundation for the further research of the gene in sex detennination.

综上所述，本项研究的创新之处在于首次通过秀丽隐杆线虫基因组用PCR方法克隆tra-1基因的锌指部分序列，不仅发现其内含子序列的组成结构对其可变性剪接有重要的影响，而且本研究结果将对克隆昆虫病原等索科线虫的相关性别决定基因提供参考价值和比较基础。

MRS2 encode a magnesium transporter protein in Saccharomyces cerevisiae and deletion of MRS2 gene results in decrease in mitochondrial magnesium concentration, Group II RNA splicing defect and growth defect on nonfermentable carbon source.

MRS2 基因编码线粒体镁离子转运蛋白，MRS2缺失会导致酵母线粒体镁离子浓度下降、线粒体内II型内含子剪接缺陷和非发酵碳源上的生长缺陷。

To obtain more information of magnesium homeostasis in mitochondria, mTn-lacZ/LEU2 transposon library was transformed into mrs2 deletion mutant to screen for suppressor genes of MRS2. YMR166C, a member of mitochondrial carrier family, was identified as a suppressor gene of MRS2. Deletion of YMR166C gene can rescue the defects of mrs2 deletion mutant such as the decrease in mitochondrial magnesium concentration, Group II RNA splicing defect and growth defect on nonfermentable carbon source. For the first time we demonstrated YMR166C is involved in mitochondrial magnesium homeostasis.

为了增进对线粒体镁离子代谢调控基因的了解，利用酿酒酵母mTn-lacZ/LEU2转座子文库筛选MRS2的抑制基因，发现线粒体载体家族成员YMR166C基因的缺失可以挽救MRS2基因缺失的突变体的生长缺陷、II型内含子剪接缺陷，并可以调节线粒体镁离子浓度，首次发现YMR166C是线粒体镁代谢相关基因。

These results show that overexpress the Tra2β1 protein may influence the propotion of the flip/flop of the AMPA receptors, and change the kinetic and ion selective of the receptors. So it can drive the development of the neural synapses.

此实验表明：过表达Tra2β1蛋白可能影响了神经细胞谷氨酸AMPA型受体flip/flop型剪接的比例，并且改变了AMPA受体的动力学和离子选择特性，从而加速了神经突触形成的发育进程。

A single point mutation in intervening sequence 2 (IVS2) of human mitochondrial arginyl-tRNA synthetase gene causes abnormal cleavage of its transcript, resulting in pontocerebellar hypoplasia.

人线粒体精氨酰-tRNA合成酶基因2号内含子中的一个单点突变导致该基因的转录本被异常剪接，造成脑桥小脑发育不全。
