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.

  • Predicted band size : 61 kDa
  • Overlay histogram showing JEG3 cells stained with ab54685 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab54685, 2µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
