Targeted mutagenesis of zebrafish: use of zinc finger nucleases

The modeling of human disease in the zebrafish (Danio rerio) is moving away from chemical mutagensis and transient downregulation using morpholino oligomers to more targeted and stable transgenic methods. In this respect, zinc finger nucleases offer a means of introducing mutations at targeted sites at high efficiency. We describe here the development of zinc finger nucleases and their general use in model systems with a focus on the zebrafish.
