Post Translational Modifications | Activated by autocatalytic proteolytical processing upon acidification. N-glycosylation is required for processing and activity. |
Function | Lysosomal serine protease with tripeptidyl-peptidase I activity. May act as a non-specific lysosomal peptidase which generates tripeptides from the breakdown products produced by lysosomal proteinases. Requires substrates with an unsubstituted N-terminus. |
