revealed the importance of the PAA(10-12) tripeptide and the ID(17-18) dipeptide, as well as the role of the PAAK(10-13) segment in nuclear localization of dUTPase.
there is a conformational shift essential for catalytic competence in the 60-kDa Drosophila melanogaster dUTPase trimer
kinetic characterization, folding, and crystallographic studies of dUTPase
dUTPase is developmentally regulated in Drosophila melanogaster
dUTPase, a recently described eukaryotic model, has a similar affinity of binding towards alpha,beta-imino-dUTP as compared to the prokaryotic E. coli enzyme
dUTPase localization character showed strict timing to the nuclear cleavage phases and explained how its isoforms can be present within the nuclear microenvironment, although at different stages of cell cycle.
A single homozygous missense mutation (chr15.hg19:g.48,626,619A>G) located in the dUTPase (DUT) gene was associated with a syndrome of bone marrow failure and diabetes.
Comparison of the cellular distribution of wild-type dUTPase with those of hyperphosphorylation- and hypophosphorylation-mimicking mutants suggests that phosphorylation at Ser11 leads to the exclusion of dUTPase from the nucleus.
EBV-encoded dUTPase may act as an intercellular signaling molecule capable of modulating the cellular microenvironment
Data sugget that inhibition of dUTPase is a mechanism-based therapeutic approach to significantly enhance the efficacy of thymidylate synthase (show TYMS Proteins) (TS)-targeted chemotherapeutic agents.
Repression of dUTPase induced specific expression level increments for thymidylate kinase (show DTYMK Proteins) and thymidine kinase (show TK1 Proteins), and also an increased sensitization to 5-fluoro-2'-deoxyuridine and 5-fluoro-uracil.
High dUTP pyrophosphatase is associated with recurrence in colorectal cancer patients undergoing 5-fluorouracil adjuvant chemotherapy
nuclear dUTPase may be a good biomarker for predicting prognosis in HCC (show FAM126A Proteins) patients after surgical resection
Novel gain of function activity of p53 (show TP53 Proteins) mutants: activation of the dUTPase gene expression leading to resistance to 5-fluorouracil.
Nuclear dUTPase may contain a complex nuclear localization signal that is located throughout the entire protein.
dUTPase staining provides a useful measure of cell proliferation distinct from that offered by Ki-67 (show MKI67 Proteins) labeling. It proved particularly useful for the evaluation of diffuse astrocytomas.
This gene encodes an essential enzyme of nucleotide metabolism. The encoded protein forms a ubiquitous, homotetrameric enzyme that hydrolyzes dUTP to dUMP and pyrophosphate. This reaction serves two cellular purposes: providing a precursor (dUMP) for the synthesis of thymine nucleotides needed for DNA replication, and limiting intracellular pools of dUTP. Elevated levels of dUTP lead to increased incorporation of uracil into DNA, which induces extensive excision repair mediated by uracil glycosylase. This repair process, resulting in the removal and reincorporation of dUTP, is self-defeating and leads to DNA fragmentation and cell death. Alternative splicing of this gene leads to different isoforms that localize to either the mitochondrion or nucleus. A related pseudogene is located on chromosome 19.
