Tartalmi leírás:
dUTPase is a dNTP sanitizing enzyme that prevents the appearance of the potentially harmful uracil bases in DNA by hydrolyzing cellular dUTP. This function of dUTPase is found to be essential in many organisms including Drosophila melanogaster. Previously we showed that the expression pattern of dUTPase determines the extent of uracil accumulation in the genome of different tissues. We wished to reveal the regulatory mechanism that eventually leaves a set of tissues to have uracil-free and intact genome. We found that the expression pattern established by the promoter of Drosophila dUTPase overlaps with mRNA and protein expression pattern, excluding the involvement of other posttranscriptional contribution. This promoter was found to be active in primordial tissues, such as in imaginal discs of the larvae, in the larval brain and in reproductive organs. In the case of brain and imaginal tissues, we observed that the promoter activity depends on DRE motifs, the docking site of DREF, which is known as a transcriptional activator of genes involved in replication and proliferation. These results suggest that dUTPase expression is fine-tuned to meet the requirements of DNA synthesis, in tissues where the maintenance of genome integrity is of high importance.
