转座因子是具有在基因组中移动的独特能力的DNA片段。这种固有的功能可以利用这些元件作为基因载体,用于不同的基因组操作。转座子为基础的遗传策略已建立在脊椎动物物种在过去的十年中,在这一领域的最新进展表明,转座因子将作为不可或缺的工具,在遗传工具包的脊椎动物模型。特别地,转座子可以用作体细胞和种系转基因的载体,以及在功能丧失和功能获得的正向诱变筛选中用作插入诱变剂。使用转座子作为遗传工具的主要优点是它们以简单、可控和可扩展的方式促进基因功能的分析。转座子为基础的技术开始被利用,以链接序列信息的基因功能在脊椎动物模型。在这篇文章中,我们提供了一个基于转座子的方法在脊椎动物模式生物的概述,并强调转座子系统的遗传应用的最重要的考虑因素。
Transposable elements are segments of DNA with the unique ability to move about in the genome. This inherent feature can be exploited to harness these elements as gene vectors for diverse genome manipulations. Transposon-based genetic strategies have been established in vertebrate species over the last decade, and current progress in this field indicates that transposable elements will serve as indispensable tools in the genetic toolkit of vertebrate models. In particular, transposons can be applied as vectors for somatic and germline transgenesis, and as insertional mutagens in both loss-of-function and gain-of-function forward mutagenesis screens. The major advantage of using transposons as genetic tools is that they facilitate analysis of gene function in an easy, controlled and scalable manner. Transposon-based technologies are beginning to be exploited to link sequence information to gene functions in vertebrate models. In this article, we provide an overview of transposon-based methods used in vertebrate model organisms, and highlight the most important considerations concerning genetic applications of the transposon systems.
