**Background of NUDT14 Recombinant Protein**
NUDT14 (Nudix Hydrolase 14) is a member of the NUDIX enzyme family, which catalyzes the hydrolysis of nucleoside diphosphate derivatives to regulate cellular nucleotide metabolism. This protein is encoded by the *NUDT14* gene located on human chromosome 19q13.2 and is evolutionarily conserved across eukaryotes. NUDT14 primarily functions in modulating nucleotide pools by hydrolyzing substrates like dATP and NADH, thereby influencing DNA repair, signaling pathways, and redox homeostasis. Dysregulation of NUDT14 has been linked to metabolic disorders and cancer, as altered nucleotide levels can impact genomic stability and cell proliferation.
Recombinant NUDT14 protein is produced via genetic engineering, often expressed in bacterial (e.g., *E. coli*) or mammalian systems to ensure proper folding and enzymatic activity. Its recombinant form enables detailed biochemical studies, including substrate specificity, kinetic analysis, and structural characterization (e.g., X-ray crystallography). Researchers utilize it to explore its role in nucleotide metabolism and interactions with therapeutic agents, particularly in oncology, where NUDT14 overexpression may contribute to drug resistance by deactivating nucleotide analog therapies. Additionally, structural insights from recombinant NUDT14 aid in designing inhibitors to modulate its activity for therapeutic purposes.
Studies on NUDT14 also highlight its potential as a biomarker or target in metabolic syndromes, given its involvement in maintaining energy balance and redox states. Its recombinant variant remains a critical tool for unraveling molecular mechanisms in nucleotide-related pathologies and advancing precision medicine strategies.
