cystatin 9 Activators

E-64 and Leupeptin serve as protease inhibitors that maintain the integrity of proteins in the extracellular matrix, upholding cystatin 9's protective role in tissue homeostasis and immune responses, respectively. The targeted inhibition of cathepsins by Cathepsin Inhibitor I further reinforce cystatin 9's regulatory function in proteolytic pathways. Calpain Inhibitor III and ALLN (Calpain Inhibitor) aid in the preservation of cellular proteins, aligning with cystatin 9's role in maintaining protein homeostasis. Pepstatin A supports cystatin 9 by limiting aspartic protease-mediated cleavage of proteins, enhancing the stabilizing effect of cystatin 9 in proteolytic regulation.

Chymostatin supports cystatin 9's modulatory role on chymotrypsin-like proteases, ensuring proper protein turnover. Antipain enhances cystatin 9's regulatory impact by inhibiting competitive protease activities, and N-ethylmaleimide indirectly enhances cystatin 9 activity by inactivating proteases through the modification of cysteine residues.
