Human HSPA5 adenoviral particles

The HSPA5 gene, also known as glucose-regulated protein 78 (GRP78) or binding immunoglobulin (BiP), encodes a key member of the heat shock protein 70 (HSP70) family. This endoplasmic reticulum (ER)-resident chaperone plays a key role in protein folding, quality control, and the unfolded protein response (UPR), ensuring that cells maintain homeostasis under stress conditions such as hypoxia, nutrient deprivation, or ER stress. HSPA5 is essential for maintaining ER function, facilitating the translocation of nascent polypeptides, and targeting misfolded proteins for degradation. In addition to its chaperone activity, HSPA5 is involved in a variety of physiological and pathological processes, including cancer progression, viral infection, and neurodegenerative diseases. Its overexpression in tumors is often associated with drug resistance and poor prognosis, making it a potential therapeutic target.

Human HSPA5 Adenoviral Particles are recombinant adenoviral vectors designed to deliver the HSPA5 gene to target cells, enabling efficient overexpression for functional studies. These particles take advantage of the high transduction efficiency and broad tropism of the adenoviral system, making them suitable for both in vitro and in vivo applications. Adenoviral HSPA5 particles are particularly valuable for studying ER stress responses, cancer biology, and neurodegenerative diseases because they enable rapid and sustained gene delivery in both dividing and non-dividing cells. In addition, they can serve as a screening tool for potential HSPA5-targeted therapeutics. Safety-modified versions, such as replication-defective adenoviruses, ensure minimal cytotoxicity while maintaining high transduction rates.
