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
    modifications
    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).

  • ab6313 staining Cathepsin D in DU145 human prostate cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with 0.1% Triton X-100 pH 7.4 and blocked with 5% BSA at room temperature for 20 minutes. Samples were incubated with primary antibody (1/200 in PBS) for 1 hour. A CF488A-conjugated goat anti-mouse IgG (H+L) polyclonal was used as the secondary antibody (1/500).

Cells were fixed with formaldehyde, permeabilized with Triton X-100 in PBS and blocked with 1% milk at room temperature for 20 minutes. Samples were incubated with primary antibody (1µg/ml in 1% milk) for 30 minutes. An undiluted Alexa Fluor® 594-conjugated goat anti-mouse IgG  polyclonal was used as the secondary antibody.
