**Background of IPO5 Recombinant Protein**
IPO5 (Importin-5), also known as RanBP5. is a member of the importin β superfamily of nuclear transport receptors. It plays a critical role in the nucleocytoplasmic transport of macromolecules, facilitating the movement of specific cargo proteins and RNA molecules between the cytoplasm and nucleus. IPO5 functions by recognizing nuclear localization signals (NLS) or other cargo-specific motifs, interacting with the Ran GTPase cycle to ensure directional transport. Structurally, it contains characteristic HEAT repeats that mediate cargo binding and regulatory interactions.
The recombinant IPO5 protein is engineered using heterologous expression systems (e.g., *E. coli*, insect cells, or mammalian cells*) to produce a purified, functional form for research applications. Its recombinant version retains the ability to bind cargoes such as ribosomal proteins, transcription factors, and viral components, making it valuable for studying nuclear import mechanisms, viral-host interactions, and cellular signaling pathways.
IPO5 has been implicated in diseases, including cancer and viral infections, where dysregulated nuclear transport contributes to pathogenesis. For example, it interacts with HIV-1 integrase and influenza virus nucleoproteins, aiding viral replication. Recombinant IPO5 is also used to develop assays for screening nuclear transport inhibitors or studying gene regulation.
In biotechnology, recombinant IPO5 is optimized for high purity and activity, often tagged with markers (e.g., His, GST) for detection and purification. Quality control involves SDS-PAGE, Western blotting, and functional assays (e.g., cargo-binding validation). Its study advances understanding of cellular trafficking and supports therapeutic development targeting transport-related disorders.
