Cathepsin S

Target (abbrv.) Cathepsin S

Somalogic ID (Sequence ID) SL004673 (3181-50_2)
Entrez Gene Symbol CTSS
UniProt ID P25774
UniProt Comment
  • Thiol protease. Key protease responsible for the removal of the invariant chain from MHC class II molecules. The bond-specificity of this proteinase is in part similar to the specificities of cathepsin L and cathepsin N.
  • Assembly of collagen fibrils and other multimeric structures
  • Degradation of the extracellular matrix
  • Endosomal/Vacuolar pathway
  • MHC class II antigen presentation
  • Trafficking and processing of endosomal TLR
Pathway Studio
  • MHC2-Mediated Antigen Presentation

All locus annotations are based on the sentinel SNP (rs41271951) and 2 proxy variant(s) that is/are in linkage disequilibrium r2 ≥ 0.8. Linkage disequilibrium is based on data from the 1000 Genomes Project, phase 3 version 5, European population and was retrieved using SNiPA's Block Annotation feature.
