Zinc-finger nucleases (ZFNs) allow targeted gene inactivation in a wide range of model organisms. We provided an archive of 81 clones containing 27 different zinc-finger modules at finger 1, 2 and 3 positions for straightforward construction of ZFNs using modular assembly-based approach. The majority of zinc-finger proteins assembled from these modules have favorable specificities and nearly one-third of modular ZFNs generated lesions at their targets in the zebra fish genome. These modules are designed for the construction of three-finger zinc-finger ZFNs, but they can also be used for assembling longer ZFNs containing 4 or more modules. We set up a website to help users search appropriate sites in their target sequences and design corresponding ZFNs using this archive:


To facilitate the application of ZFNs within the zebrafish community we constructed a public database of sites in the zebrafish genome that can be targeted using this archive:


Protocols for modular assembly construction of ZFNs can be found at the above website as well as in the following publication:
