Cystatin D/CST5, Human (HEK293, His)

Cystatin D (CST5), a cysteine proteinase inhibitor, potentially safeguards against oral cavity proteinases. Exhibiting specificity, it preferentially inhibits cathepsin S, cathepsin H, cathepsin L, and cathepsin B. This nuanced regulation emphasizes Cystatin D's role in modulating specific cysteine proteinases, signifying its importance in proteostasis and potential involvement in oral health. Cystatin D/CST5 Protein, Human (HEK293, His) is the recombinant human-derived Cystatin D/CST5 protein, expressed by HEK293 , with C-6*His labeled tag.
