MREwt 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 (BBa_K5317007) for cell-based metal-detection.
The varying Metal Responsive Elements (MREs) upstream of the eukaryotic metallothionein (MT) gene were discovered in the early 80s (Carter et al. 1984, Stuart et al. 1985). All MREs a-d carry core consensus sites (TGCRCNC) to which the primary MRE-binding transcription factor MTF-1 can bind after binding to heavy metal ions and translocating into the nucleus. Physiologically, this leads to the expression of metallothionein, a protein capable of binding metals such as zinc, cadmium, copper and others for metal homeostasis and detoxification (Cousins 1983).
