Comments
  • FUNCTION: Thiol protease which is believed to participate in intracellular degradation and turnover of proteins. Has also been implicated in tumor invasion and metastasis.
  • CATALYTIC ACTIVITY: Hydrolysis of proteins with broad specificity for peptide bonds. Preferentially cleaves -Arg-Arg-|-Xaa bonds in small molecule substrates (thus differing from cathepsin L). In addition to being an endopeptidase, shows peptidyl-dipeptidase activity, liberating C-terminal dipeptides.
  • SUBUNIT: Dimer of a heavy chain and a light chain cross-linked by a disulfide bond.
  • SUBCELLULAR LOCATION: Lysosome. Melanosome. Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
  • SIMILARITY: Belongs to the peptidase C1 family [view classification].
