4xMREa 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.
In an effort to increase the efficiency of the activated MTF1 responsive promoter, we constructed a synthetic promoter with multiple MREa sites. Searle and colleagues described 1985 that at least two MREa sites are necessary for the zinc-induced expression of the downstream gene, here herpes simplex virus thymidine kinase. They also showed that the positioning of the MREs in the promoter sequence had little effect on the promoter efficiency but was increased with more MREa sites inserted.
Cloning
Theoretical Part Design
The promoter sequence contains four MREa sites with respective core consensus sites for binding of heavy metal-activated MTF1, their positions and in-between DNA sequence based on our MREwt promoter, registry entry K5317003.
