DUT
Function
Catalyzes the cleavage of 2'-deoxyuridine 5'-triphosphate (dUTP) into 2'-deoxyuridine 5'-monophosphate (dUMP) and inorganic pyrophosphate and through its action efficiently prevents uracil misincorporation into DNA and at the same time provides dUMP, the substrate for de novo thymidylate biosynthesis (PubMed:17880943, PubMed:8631816, PubMed:8805593). Inhibits peroxisome proliferator-activated receptor (PPAR) activity by binding of its N-terminal to PPAR, preventing the latter's dimerization with retinoid X receptor (By similarity). Essential for embryonic development (By similarity).
Involvement in disease
Bone marrow failure and diabetes mellitus syndrome
BMFDMS
A form of bone marrow failure syndrome, a heterogeneous group of life-threatening disorders characterized by hematopoietic defects in association with a range of variable extra-hematopoietic manifestations. BMFDMS is an autosomal recessive form characterized by various degrees of bone marrow failure, ranging from dyserythropoiesis to bone marrow aplasia, with onset in infancy or early childhood, and non-autoimmune insulin-dependent diabetes mellitus appearing in the first or second decades. Many patients show pigmentary skin abnormalities and short stature.
None
The disease is caused by variants affecting the gene represented in this entry.
Pathway
Pyrimidine metabolism; dUMP biosynthesis; dUMP from dCTP (dUTP route): step 2/2.
Post-translational modifications
Nuclear isoform 2 is phosphorylated in vivo on Ser-11, a reaction that can be catalyzed in vitro by CDC2. Phosphorylation in mature T-cells occurs in a cell cycle-dependent manner. Isoform 3 is not phosphorylated.
Sequence Similarities
Belongs to the dUTPase family.
Tissue Specificity
Found in a variety of tissues. Isoform 3 expression is constitutive, while isoform 2 expression correlates with the onset of DNA replication (at protein level). Isoform 2 degradation coincides with the cessation of nuclear DNA replication (at protein level).
