**Background of Recombinant Human NUDT12 Protein**
NUDT12. a member of the Nudix hydrolase superfamily, is an enzyme encoded by the *NUDT12* gene in humans. Nudix proteins are characterized by a conserved catalytic motif (GX₅EX₇REUXEEXGU, where U = hydrophobic residue) and hydrolyze substrates containing a nucleoside diphosphate linked to another moiety. NUDT12 specifically catalyzes the hydrolysis of dinucleoside polyphosphates, including diadenosine tetraphosphate (Ap₄A) and NAD⁺, generating nucleotide monophosphates (e.g., AMP) and inorganic phosphate. This activity suggests roles in regulating nucleotide pool balance, stress response, and cellular signaling pathways.
Recombinant human NUDT12 is produced via heterologous expression systems (e.g., *E. coli*), enabling structural and functional studies. Structural analyses reveal a conserved Nudix fold with substrate-binding pockets tailored for diverse dinucleotides. Research highlights its potential involvement in mRNA metabolism, as it binds RNA and associates with cytoplasmic granules under stress. Dysregulation of NUDT12 has been linked to pathologies such as cancer, though its precise mechanisms remain under investigation. The recombinant protein is widely used in biochemical assays to delineate substrate specificity, enzymatic kinetics, and interactions with other macromolecules. Its study contributes to understanding nucleotide homeostasis, redox regulation, and therapeutic targeting of nucleotide-metabolizing enzymes. Key studies, including those by Jørgensen et al. (2003) and McLennan et al. (2010), have advanced insights into its biological significance and catalytic versatility.
