**Background of EXOSC2 Recombinant Protein**
EXOSC2 (Exosome Component 2) is a critical subunit of the evolutionarily conserved exosome complex, a multi-protein machinery essential for RNA processing, surveillance, and degradation. The exosome, composed of a nine-core subunit structure (EXOSC1-9) in humans, plays a central role in maintaining RNA homeostasis by regulating the quality and quantity of various RNA species, including ribosomal RNA (rRNA), messenger RNA (mRNA), and non-coding RNAs. EXOSC2. specifically, forms part of the exosome's cap structure and contributes to substrate recognition and recruitment, facilitating RNA exoribonuclease or endoribonuclease activities depending on associated catalytic subunits (e.g., DIS3 or EXOSC10).
Mutations in *EXOSC2* have been linked to human diseases, notably pontocerebellar hypoplasia type 1B (PCH1B), a severe neurodevelopmental disorder characterized by cerebellar and brainstem degeneration. Pathogenic variants, such as the recurrent p.D132A mutation, destabilize the exosome complex, impair RNA processing, and lead to aberrant neuronal development. These findings highlight EXOSC2's functional importance in neurological integrity.
Recombinant EXOSC2 protein, typically produced in bacterial or mammalian expression systems, enables in vitro studies to dissect its structural and mechanistic roles. Purified EXOSC2 is used to investigate exosome assembly, RNA-binding properties, and interactions with cofactors or disease-associated mutants. Its recombinant form also aids in structural biology (e.g., crystallography, cryo-EM) to map interfaces critical for exosome function. Furthermore, EXOSC2 recombinant proteins serve as tools for screening therapeutic compounds targeting RNA dysregulation in exosome-related disorders.
Overall, EXOSC2 recombinant protein is a vital resource for unraveling exosome biology, disease mechanisms, and potential translational applications.
