Application Abreviews Notes
  • Application notes
    WB: 1/1000 when using colorimetric substrates such as BCIP/NBT, and 1/5000 for chemiluminescent substrates. Predicted molecular weight: 46 kDa. The apparent mass may be increased due to glycosylation. Dilution optimised using Chromogenic detection. Not yet tested in other applications. Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function

      Acid protease active in intracellular protein breakdown. Involved in the pathogenesis of several diseases such as breast cancer and possibly Alzheimer disease.
    • Tissue specificity

      Expressed in the aorta extrcellular space (at protein level).
    • Involvement in disease

      Ceroid lipofuscinosis, neuronal, 10
    • Sequence similarities

      Belongs to the peptidase A1 family.
      Contains 1 peptidase A1 domain.
    • Post-translational

      N- and O-glycosylated.
    • Cellular localization

      Lysosome. Melanosome. Secreted, extracellular space. Identified by mass spectrometry in melanosome fractions from stage I to stage IV. In aortic samples, detected as an extracellular protein loosely bound to the matrix (PubMed:20551380).
