The design of novel genes encoding artificial transcription factors represents a powerful tool in biotechnology and medicine. We have engineered a new zinc finger-based transcription factor, named Blues, able to bind and possibly to modify the expression of fibroblast growth factor 4 (FGF-4, K-fgf), originally identified as an oncogene. Blues encodes a three zinc finger peptide and was constructed to target the 9 bp DNA sequence: 5′-GTT-TGG-ATG- 3′, internal to the murine FGF-4 enhancer, in proximity of Sox-2 and Oct-3 DNA binding sites. Our final aim is to generate a model system based on artificial zinc finger genes to study the biological role of FGF-4 during development and tumorigenesis.
