Synonym(s): CTSS
- CAS No.: 71965-46-3
- Formula:N/A
- Molecular Weight:N/A
SMILES: [Cathepsin S, human]
Biological Activity: Human Cathepsin S (CTSS) is a cysteine protease with elastinolytic activity. Human Cathepsin S is inhibited by cysteine protease inhibitors such as E-64 (HY-15282) and cystatin C. Human Cathepsin S cleaves substrates including elastin, TGF-β1, Myelin basic protein (HY-P1821), PAR2, SIRT1, collagen 18A1, FKN, and MHC-II invariant chain fragments, thereby driving processes such as elastic matrix degradation, TGF-β1 signaling, demyelination, PAR2-mediated calcium mobilization, NF-κB activation, hepatic fibrosis, immune homeostasis regulation, and antigen presentation. Human Cathepsin S can be used in the research of cardiovascular diseases, chronic kidney diseases, autoimmune diseases, tumors, Alzheimer's disease, and obesity[1][2][3][4][5].
