DNA-binding domains with predetermined sequence specificity are engineered by selection of zinc finger modules using phage display, allowing the construction of customized transcription factors. Despite remarkable progress in this field, the available protein-engineering methods are deficient in many respects, thus hampering the applicability of the technique. Here we present a rapid and convenient method that can be used to design zinc finger proteins against a variety of DNA-binding sites…

The results of these cell-based assays reveal that the DNA-binding specificity--in addition to the affinity--is a major determinant of ZFN activity and is inversely correlated with ZFN-associated toxicity, and provide the first evidence that engineering strategies, which account for context-dependent DNA- binding effects, yield ZFs that function as highly efficient ZFNs in human cells.
