**Background of NUDT3 Recombinant Protein**
NUDT3 (Nudix Hydrolase 3), also known as diadenosine tetraphosphate hydrolase, is a member of the NUDIX enzyme family characterized by its conserved catalytic motif (GX₅EX₇REUXEEXGU, where U represents hydrophobic residues). This family hydrolyzes substrates containing nucleoside diphosphate linked to other moieties, playing roles in nucleotide metabolism, signaling, and oxidative stress response. NUDT3 specifically catalyzes the breakdown of diadenosine tetraphosphate (Ap₄A), a signaling molecule implicated in DNA repair, apoptosis, and cellular stress adaptation.
Recombinant NUDT3 protein is produced via genetic engineering, often expressed in *E. coli* or eukaryotic systems, enabling high-purity, scalable production for research. Structural studies reveal its conserved NUDIX fold and Mg²⁺-dependent catalytic mechanism, which cleaves Ap₄A into ADP and ATP. Dysregulation of NUDT3 has been linked to diseases, including cancer (e.g., breast cancer progression) and neurodegenerative disorders (e.g., Alzheimer’s disease), where altered nucleotide pools or oxidative stress may contribute to pathology.
Research applications of recombinant NUDT3 include enzymology studies, inhibitor screening for therapeutic development, and exploring its role in cellular pathways. Its potential as a biomarker or drug target underscores its biomedical relevance. By studying recombinant NUDT3. scientists aim to unravel its physiological functions and therapeutic potential in diseases linked to nucleotide imbalance or oxidative damage.
