Recombinant human DUS3L (dihydrouridine synthase 3-like) protein is a genetically engineered form of the enzyme encoded by the *DUS3L* gene, located on chromosome 16 in humans. DUS3L belongs to the dihydrouridine synthase family, which catalyzes the reduction of uridine to dihydrouridine (D) in RNA molecules, a conserved post-transcriptional modification critical for RNA stability, conformational flexibility, and translation efficiency. Specifically, DUS3L is implicated in modifying mitochondrial tRNAs, influencing proper protein synthesis in mitochondria, and maintaining mitochondrial function. Structurally, it contains a conserved Rossmann-fold domain characteristic of NAD(P)H-dependent oxidoreductases, enabling its catalytic activity.
The recombinant protein is typically expressed in bacterial or mammalian systems for functional studies, offering a tool to explore its enzymatic mechanisms, substrate specificity, and interactions with RNA or cofactors. Research highlights its potential role in cellular stress responses and mitochondrial disorders, as disrupted DUS3L activity correlates with impaired oxidative phosphorylation and metabolic dysregulation. Additionally, aberrant expression has been linked to certain cancers and neurodegenerative conditions, though mechanistic insights remain preliminary.
Studying recombinant DUS3L aids in elucidating its biological significance in RNA modification pathways and may contribute to therapeutic strategies targeting mitochondrial dysfunction or RNA-mediated diseases. Its applications extend to biochemical assays, drug screening, and structural biology to uncover novel inhibitors or modulators.
