背景信息

The heterogeneous nuclear ribonucleoprotein H2 (HNRNPH2) is a member of the HNRNP family, which plays critical roles in RNA metabolism, including pre-mRNA splicing, transport, stability, and translation regulation. HNRNPH2 specifically binds to RNA through its RNA recognition motifs (RRMs), facilitating interactions with GU-rich sequences or splice site elements. It is involved in alternative splicing decisions, influencing the diversity of mRNA isoforms and protein products. Dysregulation of HNRNPH2 has been linked to neurodevelopmental disorders, such as X-linked intellectual disability, and certain cancers, highlighting its importance in cellular homeostasis and disease.

Recombinant HNRNPH2 protein is engineered using heterologous expression systems (e.g., *E. coli* or mammalian cells) to produce functional, purified protein for *in vitro* studies. Its recombinant form enables detailed biochemical and structural analyses, such as elucidating RNA-binding specificity, mapping interaction domains, or screening for small-molecule modulators. Researchers utilize affinity tags (e.g., His-tag) for efficient purification and detection. Studies leveraging recombinant HNRNPH2 have advanced understanding of its role in RNA processing mechanisms and pathogenicity of mutations. Additionally, it serves as a tool for developing therapeutic strategies targeting splicing defects or HNRNPH2-associated pathways. The protein’s conserved functional domains and disease relevance make it a focal point in both basic and translational research.
