EXOSC5. also known as Rrp46 or p10. is a critical subunit of the evolutionarily conserved exosome complex, a multi-protein machinery responsible for RNA processing, degradation, and quality control in eukaryotic cells. As a core component of the exosome’s nine-subunit catalytically inactive ring structure, EXOSC5 plays a structural and regulatory role in maintaining the complex’s stability and guiding substrate specificity. It belongs to the S1/KH-domain protein family, characterized by RNA-binding motifs that facilitate interactions with RNA molecules during 3'→5' exoribonuclease activities mediated by associated catalytic subunits (e.g., DIS3/RRP44).
Recombinant EXOSC5 protein is produced using heterologous expression systems, such as *E. coli* or mammalian cell lines, enabling detailed biochemical and functional studies. Its recombinant form allows researchers to investigate exosome assembly, RNA-binding properties, and interactions with partner proteins or cofactors. Mutational analyses using recombinant EXOSC5 have helped identify residues critical for RNA recognition and complex integrity. Dysregulation of exosome components, including EXOSC5. has been linked to human diseases, such as pontocerebellar hypoplasia, neurodegenerative disorders, and cancers, making this protein a focus for therapeutic exploration. Recombinant EXOSC5 is also utilized in structural studies (e.g., cryo-EM) to map exosome architecture and in high-throughput screens for small-molecule inhibitors targeting exosome-related pathologies. Its production often includes affinity tags (e.g., His-tag) for purification, ensuring high yield and purity for experimental reproducibility. Research on EXOSC5 continues to shed light on RNA metabolism mechanisms and their implications in cellular homeostasis and disease.
