CUP1 promoter

This is the full length of CUP1 promoter in yeast Saccharomyces cerevisiae. As the major copper-activated metallothionine in yeast, Cup1p binds and sequesters cuprous copper(I), Cu+, providing the principal method of removing this metal ion from the cell. CUP1 transcription is specifically induced by the copper-dependent transcription activator Cup2p (more commonly known as Ace1p) in response to high levels of copper ions and by Hsf1p in response to heat shock, glucose starvation and oxidation stress. In the presence of copper, Cup1p is also capable of antioxidant activity and thus contributes a significant, albeit minor, role to oxygen radical detoxification, especially in the absence of Cu,Zn-superoxide dismutase Sod1p.

Characterization

Toulouse_INSA_UPS_2021contributed to the characterization of this part. The CUP1 promoter, inducible by the addition of copper in the medium, had not been characterized before, but the team showed this year that it is functional for expression in S. cerevisiae. To do this the promoter was placed upon the dbr1 gene, allowing the production of dihydro-β-ionone and this molecule was indentified thanks to GC-MS approaches. Check the part of the full construction (BBa_K3930000) for more result details.
