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 (By similarity). {ECO:0000250}.
|
Subcellular Location |
Lysosome. Melanosome. Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
|
Tissue Specificity |
Detected in all tissues examined with highest levels in heart and placenta and relatively similar levels in other tissues.
