**Background of NUDT9 Recombinant Protein**
NUDT9. a member of the Nudix hydrolase superfamily, is a cytosolic enzyme encoded by the *NUDT9* gene in humans. It primarily hydrolyzes adenosine diphosphate ribose (ADP-ribose), a signaling molecule involved in cellular processes like calcium regulation, DNA repair, and energy metabolism. NUDT9’s catalytic activity relies on its conserved Nudix motif, which enables magnesium-dependent cleavage of ADP-ribose into AMP and ribose-5-phosphate. This function links NUDT9 to maintaining cellular ADP-ribose homeostasis, preventing its accumulation, which may otherwise interfere with signaling pathways or induce oxidative stress.
Recombinant NUDT9 protein is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), allowing researchers to study its structure, enzymatic kinetics, and interactions in vitro. Structural studies reveal a characteristic α/β-fold common to Nudix enzymes, with a flexible loop near the active site influencing substrate specificity. Unlike other Nudix members (e.g., NUDT1 or NUDT15), NUDT9 shows narrow substrate selectivity, primarily targeting ADP-ribose and its derivatives.
Research highlights its role in metabolic disorders and neurodegenerative diseases. For instance, altered ADP-ribose levels due to NUDT9 dysfunction may disrupt calcium signaling in mitochondria, potentially contributing to pathologies like type 2 diabetes or Alzheimer’s disease. Additionally, NUDT9’s interaction with the hormone-sensitive lipase (HSL) in adipocytes suggests involvement in lipid metabolism, expanding its relevance to obesity-related studies.
The recombinant protein is widely used in drug discovery to screen inhibitors or modulators targeting ADP-ribose metabolism. Its role in cancer remains underexplored but emerging evidence implicates NUDT9 in chemoresistance mechanisms, prompting interest in therapeutic targeting. Overall, NUDT9 recombinant protein serves as a vital tool for unraveling the enzyme’s biological significance and translational potential.
