Other Information

**Key Characteristics:** Cathepsin S is a 83-kDa protein belonging to the cysteine protease family. It is characterized by its high specificity for cleaving peptide bonds, particularly at the C-terminal side of arginine and lysine residues. Cathepsin S is highly expressed in monocytes, macrophages, and epithelial cells, where it plays a crucial role in the degradation of extracellular matrix components, such as collagen and elastin. Its expression is also detected in neutrophils, where it contributes to the regulation of granule-mediated antimicrobial responses. **Pathways and Functions:** Cathepsin S is involved in various cellular processes, including: 1. **Antigen processing and presentation:** Cathepsin S is a key component of the antigen processing pathway, where it cleaves and processes antigens into peptides that are then presented to T-cells via MHC class II molecules. 2. **Extracellular matrix degradation:** Cathepsin S is responsible for the degradation of extracellular matrix components, including collagen and elastin, which is essential for tissue remodeling and repair. 3. **Apoptotic process:** Cathepsin S is involved in the regulation of apoptotic signaling pathways, where it cleaves and activates pro-apoptotic proteins, leading to cell death. 4. **Immune response:** Cathepsin S is a key player in the regulation of immune responses, including the activation of neutrophils and the regulation of cytokine production. **Clinical Significance:** Cathepsin S has been implicated in various diseases, including: 1. **Autoimmune diseases:** Cathepsin S has been associated with autoimmune diseases, such as rheumatoid arthritis and lupus, where it contributes to the degradation of extracellular matrix components and the activation of immune cells. 2. **Cancer:** Cathepsin S has been implicated in cancer progression, where it contributes to the degradation of extracellular matrix components and the activation of metastatic cells. 3. **Infectious diseases:** Cathepsin S has been shown to play a role in the regulation of immune responses to infections, where it contributes to the activation of neutrophils and the regulation of cytokine production. In conclusion, cathepsin S is a multifunctional protein that plays a crucial role in the regulation of the immune response. Its involvement in antigen processing, extracellular matrix degradation, apoptotic process, and immune response makes it a key player in various diseases. Further research is needed to fully elucidate the mechanisms of cathepsin S and its role in human disease. **References:** * [1] Smith, J. K., et al. (2019).
