背景信息

**Background of HNRNPA2B1 Recombinant Protein**

HNRNPA2B1 (heterogeneous nuclear ribonucleoprotein A2/B1) is a member of the hnRNP family, which plays critical roles in RNA metabolism, including splicing, transport, stability, and translation. This protein is ubiquitously expressed and localizes predominantly in the nucleus, where it interacts with nascent RNA transcripts. Structurally, HNRNPA2B1 contains two RNA recognition motifs (RRMs) that mediate binding to specific RNA sequences and a glycine-rich domain involved in protein-protein interactions.

The recombinant form of HNRNPA2B1 is engineered for in vitro studies to dissect its molecular functions. Produced using expression systems like *E. coli* or mammalian cells, the recombinant protein retains key functional domains, enabling researchers to explore its role in RNA processing, DNA repair, and innate immune signaling. Notably, HNRNPA2B1 has been implicated in recognizing viral nucleic acids, triggering antiviral responses via the cGAS-STING pathway, and regulating immune-related gene expression.

Research using recombinant HNRNPA2B1 has also highlighted its involvement in diseases. Dysregulation of HNRNPA2B1 is linked to cancer progression, neurodegenerative disorders (e.g., amyotrophic lateral sclerosis), and autoimmune conditions. Its ability to form stress granules or amyloid-like aggregates under pathological conditions makes it a focus in studying protein misfolding diseases.

Recombinant HNRNPA2B1 is widely utilized in biochemical assays, structural studies (e.g., crystallography), and drug screening to identify modulators targeting its RNA-binding or aggregation-prone regions. Additionally, it serves as an antigen for antibody development in diagnostic applications. Understanding HNRNPA2B1's mechanisms through recombinant protein studies offers insights into therapeutic strategies for diseases linked to RNA processing defects or aberrant immune signaling.
