**Background of Recombinant Human AHSA2 Protein**
The Activator of HSP90 ATPase Activity 2 (AHSA2) is a co-chaperone protein that regulates the function of Heat Shock Protein 90 (HSP90), a molecular chaperone critical for maintaining cellular proteostasis. AHSA2 directly interacts with HSP90 to modulate its ATPase activity, influencing the conformational cycling required for client protein maturation, including kinases, transcription factors, and steroid hormone receptors.
Recombinant human AHSA2 protein is engineered using heterologous expression systems (e.g., *E. coli* or mammalian cells*) to enable functional and structural studies. Its production allows researchers to investigate molecular mechanisms underlying HSP90-dependent pathways, particularly in diseases like cancer, where HSP90 client proteins often drive tumor progression. AHSA2’s role in stress response and protein quality control also links it to neurodegenerative disorders and cellular adaptation to environmental stress.
Research on recombinant AHSA2 has advanced understanding of HSP90 chaperone machinery dynamics, offering potential therapeutic avenues. Inhibitors targeting HSP90-AHSA2 interactions are being explored for cancer therapy. Additionally, recombinant AHSA2 serves as a tool to study post-translational modifications, protein-protein interactions, and chaperone network dysregulation in pathological conditions. Its applications extend to drug screening and elucidating resistance mechanisms in HSP90-targeted therapies.
