    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).
