CMV-MTF1-mRuby2

Usage and Biology

The Metal Regulatory Transcription Factor 1 (MTF-1) is a metal ion-sensing transcription factor, regulating primarily zinc, cadmium and copper homeostasis and detoxification (Tavera-Montañez et al. 2019, Wimmer et al. 2005). Activation of MTF-1 due to increasing levels of heavy metals in the cytoplasm results in its translocation into the nucleus and binding via its zinc finger domains to MREs, specifically consensus TGCRCNC in promoter regions of the DNA. Thereby MTF-1 regulates expression of metallothioneins, metal transporters, and antioxidant genes as protection against metal toxicity and oxidative stress (Tavera-Montañez et al. 2019). Additional stimuli of MTF-1 nucleus import are stress signals such as heat shock, H2O2, low extracellular pH (Saydam et al. 2001).
