**Background of RRM1 Recombinant Protein**
Ribonucleotide reductase M1 subunit (RRM1) is a critical regulatory component of ribonucleotide reductase (RNR), an enzyme essential for DNA synthesis and repair. RNR catalyzes the conversion of ribonucleotides to deoxyribonucleotides, the building blocks of DNA, thereby playing a pivotal role in cell proliferation and genome stability. RRM1. along with its catalytic partner RRM2 (or RRM2B in some contexts), forms the active RNR holoenzyme. While RRM2 provides the radical necessary for catalysis, RRM1 governs substrate specificity, allosteric regulation, and overall enzyme activity.
RRM1 has garnered significant attention in cancer research due to its dual role in DNA metabolism and cancer progression. Overexpression of RRM1 is linked to tumor aggressiveness, resistance to chemotherapeutic agents (e.g., gemcitabine), and poor prognosis in cancers such as lung, breast, and pancreatic malignancies. Conversely, its dysregulation can disrupt nucleotide balance, leading to genomic instability. These features make RRM1 a potential therapeutic target and a biomarker for predicting treatment response.
Recombinant RRM1 protein is produced using expression systems like *E. coli* or mammalian cells, enabling studies on its structure, function, and interactions. Purification techniques often involve affinity tags (e.g., His-tag) followed by chromatography. The recombinant protein is widely utilized in *in vitro* assays to screen RNR inhibitors, investigate enzyme kinetics, and explore mechanisms of drug resistance. Additionally, structural studies using recombinant RRM1 have advanced understanding of RNR’s regulatory mechanisms, aiding the design of targeted therapies.
Beyond oncology, RRM1’s role in viral DNA replication (e.g., herpesviruses) highlights its broader biomedical relevance. Overall, recombinant RRM1 serves as a vital tool for dissecting RNR biology and developing strategies to modulate its activity in disease contexts.
