Ruby fused with AGA2 under the control of the ADH1 promoter
Description
mRuby2 can be used as a reporter system. Here, mRuby2 was used as a transcriptional reporter, to control the transcriptional efficiency of the yeast promoter pADH1. The excitation wavelength is 559nm and the emission wavelength is 600nm.
Modifier
Details of the System Function
By quantifying the fluorescence emitted by the cells, we can assess the strength of the promoter, which is crucial in our case to maximize the amount of secreted protein. We have constructed a similar setup using a different strong promoter and another fluorescent protein to compare the promoters. Using the AGA2 pre-peptide, we can determine whether the protein is effectively secreted into the extracellular medium. To achieve this, we will measure the fluorescence in the culture supernatant and verify whether proteins have been produced and secreted. The His tag will enable us to perform Western blots to confirm our results.
Construction
The gene encoding the chimeric mRuby2 protein fused to AGA2 and 6HIS-Tag has been optimized for synthesis and expression in Saccharomyces cerevisiae. We have placed this coding region downstream of the ADH1promoter to ensure strong constitutive expression. The entire construct has been synthesized.
This genetic construct has been cloned into the following plasmid backbone:
Resulting in the following integrative plasmid:
