| Application: | Active human cathepsin F is useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling. Active human cathepsin F has been used in a study to assess its implications for the development of novel immunomodulators. Active human cathepsin F has also been used in a study to investigate microarray expression analysis and identification of serum biomarkers for Niemann-Pick disease. |
| Biochem/physiol Actions: | Cathepsin F (CtsF) are endopeptidases that play a role in lysosomal protein degradation. Beyond its involvement in protein recycling, CtsF has also been associated with immune responses mediated by Toll-like receptors (TLRs) and antigen processing. Additionally, mutation in the cathepsin F gene is related to the development of familial papillary thyroid cancer , type B Kufs disease, defective lysosomal degradation and abnormal autophagy, and Alzheimer′s disease. |
