4xMREd promoter
Usage and Biology
The MRE-sites containing promoter enables the metal-dependent expression of a downstream positioned reporter gene via the metal ion-dependent transcription factor MTF-1 for cell-based metal detection.
To achieve a cell-based heavy metal sensor, our group generated multiple synthetic MTF1 responsive promoter constructs and tested them in regard to their efficiency. Since Wang and colleagues (2004) suggested a high affinity of MTF-1 towards MREd we synthesized a promoter sequence containing four MREd elements at the positioning of the MREs of the MREwt promoter [1] to exclude possible disruption of the MTF-1 and MRE interaction.
Cloning
Theoretical Part Design
The sequence of the MREd site was obtained from Seguin and colleagues (1987), as well as the positioning and spacer sequences (Searle et al. 1985). The construct was synthesized.
