Genome engineering with targetable nucleases.
Current technology enables the production of highly specific genome modifications with excellent efficiency and specificity. Key to this capability are targetable DNA cleavage reagents and cellular DNA repair pathways. The break made by these reagents can produce localized sequence changes through inaccurate nonhomologous end joining (NHEJ), often leading to gene inactivation. Alternatively, us...
متن کاملGenome engineering with zinc-finger nucleases.
Zinc-finger nucleases (ZFNs) are targetable DNA cleavage reagents that have been adopted as gene-targeting tools. ZFN-induced double-strand breaks are subject to cellular DNA repair processes that lead to both targeted mutagenesis and targeted gene replacement at remarkably high frequencies. This article briefly reviews the history of ZFN development and summarizes applications that have been m...
متن کاملMouse Genome Engineering Using Designer Nucleases
Transgenic mice carrying site-specific genome modifications (knockout, knock-in) are of vital importance for dissecting complex biological systems as well as for modeling human diseases and testing therapeutic strategies. Recent advances in the use of designer nucleases such as zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and the clustered regularly in...
متن کاملTranscription activator-like effector nucleases enable efficient plant genome engineering.
The ability to precisely engineer plant genomes offers much potential for advancing basic and applied plant biology. Here, we describe methods for the targeted modification of plant genomes using transcription activator-like effector nucleases (TALENs). Methods were optimized using tobacco (Nicotiana tabacum) protoplasts and TALENs targeting the acetolactate synthase (ALS) gene. Optimal TALEN s...
متن کاملGenome editing with engineered nucleases in plants.
Numerous examples of successful 'genome editing' now exist. Genome editing uses engineered nucleases as powerful tools to target specific DNA sequences to edit genes precisely in the genomes of both model and crop plants, as well as a variety of other organisms. The DNA-binding domains of zinc finger (ZF) proteins were the first to be used as genome editing tools, in the form of designed ZF nuc...
