**Background of NMNAT1 Recombinant Protein**
NMNAT1 (Nicotinamide Nucleotide Adenylyltransferase 1) is a ubiquitously expressed enzyme that catalyzes the final step in the biosynthesis of nicotinamide adenine dinucleotide (NAD⁺), a critical coenzyme involved in cellular energy metabolism, DNA repair, and signaling pathways. As one of three NMNAT isoforms in humans, NMNAT1 is distinct in its nuclear localization and role in maintaining NAD⁺ homeostasis, particularly in metabolically active or stressed cells. Dysregulation of NMNAT1 has been linked to neurodegenerative disorders, such as Alzheimer’s and Parkinson’s diseases, as well as retinal degeneration, highlighting its importance in neuronal survival and function.
Recombinant NMNAT1 protein is engineered using genetic cloning techniques, typically expressed in *E. coli* or mammalian cell systems*,* to ensure high purity and functional activity. Its production enables researchers to study the enzyme’s structure, substrate specificity, and interactions with other proteins or small molecules. Notably, NMNAT1 exhibits neuroprotective properties independent of its enzymatic activity, suggesting additional chaperone-like roles in protein quality control. This dual functionality makes it a compelling therapeutic target for conditions involving axonal degeneration or mitochondrial dysfunction.
In research, NMNAT1 recombinant protein is utilized to investigate mechanisms of NAD⁺ depletion in aging, metabolic disorders, and neurodegeneration. It also serves as a tool for drug discovery, screening compounds that modulate NAD⁺ synthesis or enhance cellular stress resilience. Recent studies emphasize its potential in delaying age-related pathologies by boosting NAD⁺ levels, offering avenues for developing therapies against diseases driven by metabolic decline.
Overall, NMNAT1 recombinant protein bridges fundamental research and translational applications, providing insights into cellular health and strategies to combat NAD⁺-related disorders.
