pRAD27-AhR - receptor module
The pRAD27-AhR receptor module integrates the Aryl Hydrocarbon Receptor (AhR) () with the pRAD27 promoter (), creating a system that is responsive to both environmental toxins and cellular stress related to DNA repair processes. The pRAD27 promoter is derived from the RAD27 gene, which is involved in DNA repair and replication in yeast, particularly in the processing of Okazaki fragments during DNA synthesis.
In this composite module, the pRAD27 promoter controls the expression of AhR, a ligand-activated transcription factor that senses and responds to environmental contaminants such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and dioxins. When these toxins bind to AhR, the receptor translocates to the nucleus, where it dimerizes with the Aryl hydrocarbon receptor nuclear translocator (ARNT). This complex then binds to xenobiotic response elements (XREs) in the DNA, activating the transcription of detoxification genes, such as those coding for cytochrome P450 enzymes, which metabolize and neutralize harmful compounds.
