Target

  • 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.

  • Tissue specificity

    Detected in all tissues examined with highest levels in heart and placenta and relatively similar levels in other tissues.

  • Involvement in disease

    Defects in TPP1 are the cause of neuronal ceroid lipofuscinosis type 2 (CLN2) [MIM:204500]. A form of neuronal ceroid lipofuscinosis. Neuronal ceroid lipofuscinoses are progressive neurodegenerative, lysosomal storage diseases characterized by intracellular accumulation of autofluorescent liposomal material, and clinically by seizures, dementia, visual loss, and/or cerebral atrophy. The lipopigment pattern seen most often in CLN2 consists of curvilinear profiles.

  • Sequence similarities

    Belongs to the peptidase S53 family.

  • Post-translational
    modifications

    Activated by autocatalytic proteolytical processing upon acidification. N-glycosylation is required for processing and activity.

  • Cellular localization

    Lysosome. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
  • Information by UniProt
