Protein Name: Dipeptidyl peptidase 1

UniprotKB/SwissProt ID: P80067 (P80067)

Gene Name: Ctsc

Organism: Rattus norvegicus (Rat)

Function: Thiol protease (PubMed:1740150). Has dipeptidylpeptidase activity (PubMed:1740150). Active against a broad range of dipeptide substrates composed of both polar and hydrophobic amino acids. Proline cannot occupy the P1 position and arginine cannot occupy the P2 position of the substrate (PubMed:1740150). Can act as both an exopeptidase and endopeptidase (By similarity). Activates serine proteases such as elastase, cathepsin G and granzymes A and B (By similarity)

Protein Subcellular Localization: Lysosome
