Human KPNA4 adenoviral particles

The KPNA4 gene, also known as karyopherin alpha subunit 4, encodes a key member of the importin alpha family and plays a key role in nuclear transport. The protein facilitates the transport of specific cargo proteins from the cytoplasm to the nucleus by recognizing nuclear localization signals (NLS). KPNA4 is involved in immune responses, cell cycle regulation, and viral infection, particularly through its interactions with viral proteins and transcription factors. Studies have linked KPNA4 to inflammatory pathways and cancer progression. Due to its broad substrate specificity and functional diversity, KPNA4 is an important target for gene therapy, cell signaling, and disease mechanism studies.

Human KPNA4 adenoviral particles are genetically engineered viral vectors designed to deliver the KPNA4 gene to target cells for expression. These particles are based on replication-defective adenoviruses, ensuring efficient transduction while minimizing cytotoxicity. The adenoviral system provides high infection efficiency in a variety of cell types, including primary cells and cells that are difficult to transfect. After infection, the delivered KPNA4 gene is integrated into the host cell''s transcriptional machinery, resulting in stable and sustained expression of the KPNA4 protein. These particles are widely used in functional studies to investigate nuclear transport mechanisms, immune regulation, and disease-related pathways. In addition, they are also valuable tools in gene therapy research, especially in exploring the role of KPNA4 in cancer, viral infection, and inflammatory diseases.
