**Background of NUBP1 Recombinant Protein**
NUBP1 (Nucleotide-Binding Protein 1), also known as cytosolic Fe-S cluster assembly factor 1. is a member of the NUBP/MRP subfamily of ATP-binding proteins. It plays a critical role in cellular iron-sulfur (Fe-S) cluster biogenesis, a conserved process essential for the function of numerous enzymes involved in DNA repair, mitochondrial respiration, and redox regulation. Fe-S clusters act as cofactors for proteins critical to genome stability, energy metabolism, and cellular homeostasis. NUBP1. along with its homolog NUBP2. forms a heterotetrameric complex that facilitates the assembly and transfer of Fe-S clusters to target apoproteins, ensuring their proper maturation and activity.
Recombinant NUBP1 protein is engineered for in vitro studies to dissect its molecular mechanisms, interactions, and structural properties. Produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), it enables researchers to investigate its ATPase activity, Fe-S cluster binding, and role in cytosolic/nuclear Fe-S protein maturation. This recombinant tool is pivotal for exploring NUBP1's regulatory functions in cell cycle progression, particularly its involvement in mitotic spindle formation and chromosome segregation.
Structurally, recombinant NUBP1 often includes affinity tags (e.g., His-tag, GST) for purification and detection. Studies using this protein have linked NUBP1 dysregulation to pathological conditions, including cancers (e.g., colorectal, breast) and neurodegenerative disorders, where Fe-S cluster deficiency disrupts cellular metabolism. Additionally, its interaction with components of the DNA damage response pathway highlights its potential as a therapeutic target.
Overall, NUBP1 recombinant protein serves as a vital resource for advancing understanding of Fe-S cluster biology, cellular stress responses, and disease mechanisms, offering a foundation for drug discovery and functional genomics research.
