Protein Structure
UniProt Annotation
Function Dihydrouridine synthase. Catalyzes the synthesis of dihydrouridine, a modified base found in the D-loop of most tRNAs. Negatively regulates the activation of EIF2AK2/PKR. {ECO:0000269PubMed:15994936, ECO:0000269PubMed:18096616}.
Subcellular Localization Cytoplasm {ECO:0000269PubMed:15994936}. Endoplasmic reticulum {ECO:0000269PubMed:15994936}. Note=Mainly at the endoplasmic reticulum.
Disease Associations
Tissue Specificity Weak expression in heart, placenta and skeletal muscle. Up-regulated in most lung cancer cells (at protein level). {ECO:0000269PubMed:15994936}.
