Recombinant human HNRPF (heterogeneous nuclear ribonucleoprotein F) is a protein involved in multiple aspects of RNA metabolism, including splicing, transport, and stability. As a member of the hnRNP family, HNRPF plays a critical role in gene expression regulation by binding to RNA molecules through its RNA recognition motifs (RRMs). It is particularly known for interacting with G-tract sequences in pre-mRNA, influencing splice site selection and alternative splicing events. Dysregulation of HNRPF has been linked to cancers, neurodegenerative diseases, and viral infections, highlighting its functional significance.
Recombinant HNRPF is typically produced in *E. coli* or mammalian expression systems, enabling studies of its biochemical properties, structural interactions, and cellular mechanisms. Its structure includes three RRM domains and a C-terminal glycine-rich region essential for protein-protein interactions. Researchers utilize recombinant HNRPF to investigate its role in RNA processing, disease pathogenesis, and potential therapeutic targeting. Additionally, studies explore its isoforms and post-translational modifications, which modulate its activity in stress responses and cell cycle regulation. Understanding HNRPF’s functions provides insights into RNA-driven disease mechanisms and opportunities for biomedical applications.
