Engineering Transcription Factors to Selectively Control Gene Expression
The C2-H2 class of zinc finger DNA binding domains has provided a structural basis for the design and assembly of DNA binding proteins with novel sequence specificities. Methods for high-throughput assembly and biochemical characterization of these novel proteins has led to a better understanding of their binding properties. Using reiterative design processes, proteins having singular site specificity over a range of 18 basepairs have been produced. By combining these targeting proteins with transcriptional activation and repression domains, gene specific transcription factors have been made. These transcription factors have the ability to both up- and down-regulate the expression of the gene to which they are targeted. The technology is being applied in cellular and animal models for the determination of gene function and validation of gene targets for pharmaceutical drug development
