Custom Zinc-Finger Nucleases for Use in Human Cells

Open access

Abstract

Genome engineering through homologous recombination (HR) is a powerful instrument for studying biological pathways or creating treatment options for genetic disorders. In mammalian cells HR is rare but the creation of targeted DNA double-strand breaks stimulates HR significantly. Here, we present a method to generate, evaluate, and optimize rationally designed endonucleases that promote HR. The DNA-binding domains were synthesized by assembling predefined zinc-finger modules selected by phage display. Attachment of a transcriptional activation domain allowed assessment of DNA binding in reporter assays, while fusion with an endonuclease domain created custom nucleases that were tested for their ability to stimulate HR in episomal and chromosomal gene repair assays. We demonstrate that specificity, expression kinetics, and protein design are crucial parameters for efficient gene repair and that our two-step assay allows one to go quickly from design to testing to successful employment of the custom nucleases in human cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
