青鳉鱼Tol2元件是一个自主转座子,编码一个功能齐全的转座酶。转座酶蛋白可以催化转座子构建体的转座,所述转座子构建体分别具有来自Tol2序列的左端和右端的200和150个碱基对的DNA。这些序列含有必需的末端反向重复序列和亚末端序列。可以在这些序列之间克隆相当大尺寸的DNA插入物(大至11个内切酶)而不降低转座活性。Tol2转座子系统已被证明在迄今为止测试的所有脊椎动物细胞中是有活性的,包括斑马鱼、爪蟾、鸡、小鼠和人。在这篇综述中,我描述并讨论了如何Tol2转座子被应用于这些脊椎动物的转基因研究,以及未来可能的应用。
The medaka fish Tol2 element is an autonomous transposon that encodes a fully functional transposase. The transposase protein can catalyze transposition of a transposon construct that has 200 and 150 base pairs of DNA from the left and right ends of the Tol2 sequence, respectively. These sequences contain essential terminal inverted repeats and subterminal sequences. DNA inserts of fairly large sizes (as large as 11 kilobases) can be cloned between these sequences without reducing transpositional activity. The Tol2 transposon system has been shown to be active in all vertebrate cells tested thus far, including zebrafish, Xenopus, chicken, mouse, and human. In this review I describe and discuss how the Tol2 transposon is being applied to transgenic studies in these vertebrates, and possible future applications.
