Team Estonia_TUIT characterization of BBa_K3748015 (pREV1)
pREV1 is a constitutive promoter responsible for the expression of REV1, a gene encoding bi-functional DNA-directed DNA polymerase/deoxycytidyl transferase (Lee et al., 2015). This enzyme is involved in error-prone translesion synthesis, one of the pathways for DNA repair (Lawrence, 2004).
We quantified the expression driven by pREV1 using fluorescent proteins as reporter genes. The expression cassettes were integrated into the yeast genome, and the fluorescence of the reporter proteins was monitored by quantitative time-lapse microscopy. The fluorescence levels were compared to the cell background fluorescence of the control DOM90 strain, which does not express any fluorescent proteins
pREV1 promoters showed a constitutive level of Venus fluorescence throughout the experiment, confirming that it is a constitutive promoter. Compared to the background fluorescence of the DOM90 strain pREV1 demonstrated a five-fold higher level of fluorescence intensity (Figure 1).
