Synthetic cell-or tissue-specific transcriptional regulatory regions
View Patent ↗The invention concerns making and evaluating synthetic regulatory regions for controlling gene expression. The invention features a method for identifying transcription factor binding sites and a method for evaluating the regulatory functions of synthetic regulatory regions.
1. A muscle specific promoter comprising a synthetic regulatory region comprising an arrangement of at least three different transcription factor binding sites selected from the group consisting of SRE, MEF-1, MEF-2, TEF-1, Sp1, and combinations thereof.
2. The muscle specific promoter of claim 1 , wherein the synthetic regulatory region comprises at least one copy of SRE, MEF-1, and MEF-2.
3. The muscle specific promoter of claim 2 , further comprising at least one copy of TEF1.
4. The muscle specific promoter of claim 2 , further comprising at least one copy of Sp1.
