**Background of ABCE1 Recombinant Protein**
ABCE1 (ATP-binding cassette sub-family E member 1) is a conserved eukaryotic protein belonging to the ATP-binding cassette (ABC) transporter superfamily. Unlike most ABC proteins, ABCE1 lacks transmembrane domains and does not function as a classical transporter. Instead, it plays critical roles in cellular processes such as translation termination, ribosome biogenesis, and RNA metabolism. Structurally, ABCE1 contains two nucleotide-binding domains (NBDs) that hydrolyze ATP, along with an iron-sulfur (FeS) cluster domain essential for its activity.
ABCE1 is crucial for ribosome recycling, where it collaborates with release factors to dissociate ribosomal subunits after translation. This function links it to protein synthesis regulation and cellular stress responses. Additionally, ABCE1 interacts with viral RNAs and host factors, implicating it in innate immunity and antiviral defense. Its role in suppressing RNA virus replication has garnered interest in virology and immunology research.
Aberrant ABCE1 expression is associated with cancers, including lung, breast, and colorectal cancer, where it may promote proliferation and metastasis. Studies also suggest its involvement in maintaining cancer stem cell properties, making it a potential therapeutic target.
Recombinant ABCE1 protein, produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), retains ATPase activity and structural integrity, enabling functional studies. Its applications span structural biology (e.g., crystallography to resolve mechanistic details), biochemical assays (e.g., ribosome interaction studies), and drug screening for antiviral or anticancer therapies. Challenges in its production include maintaining FeS cluster stability and avoiding aggregation, often addressed through fusion tags or co-expression with chaperones.
Overall, ABCE1 recombinant protein serves as a vital tool for elucidating its multifaceted roles in translation, viral pathogenesis, and oncogenesis, with translational implications for therapeutic development.
