Designer DNA-binding proteins based on transcriptional activator-like effectors (TALEs) and zinc finger proteins (ZFPs) are easily tailored to recognize specific DNA sequences in a modular manner. They can be engineered to generate tools for targeted genome perturbation. Here, we review recent advances in these versatile technologies with a focus on designer nucleases for highly precise, efficient, and scarless gene modification. By generating double stranded breaks and stimulating cellular DNA repair pathways, TALE and ZF nucleases have the ability to modify the endogenous genome. We also discuss current applications of designer DNA-binding proteins in synthetic biology and disease modeling, novel effector domains for genetic and epigenetic regulation, and finally perspectives on using customizable DNA-binding proteins for interrogating neural function.
基于转录激活因子样效应物(TALEs)和锌指蛋白(ZFPs)的设计 DNA 结合蛋白可以轻松地进行模块化改造,以识别特定的 DNA 序列。它们可以被设计成用于靶向基因组扰动的工具。在这里,我们综述了这些多功能技术的最新进展,重点是用于高度精确、高效和无痕基因修饰的设计核酸酶。通过产生双链断裂并刺激细胞 DNA 修复途径,TALE 和 ZF 核酸酶能够修饰内源性基因组。我们还讨论了设计 DNA 结合蛋白在合成生物学和疾病建模中的当前应用、用于遗传和表观遗传调控的新型效应结构域,以及最后关于使用可定制 DNA 结合蛋白来研究神经功能的观点。
