Target

  • Function

    Closely involved in osteoclastic bone resorption and may participate partially in the disorder of bone remodeling. Displays potent endoprotease activity against fibrinogen at acid pH. May play an important role in extracellular matrix degradation.
  • Tissue specificity

    Predominantly expressed in osteclasts (bones).
  • Involvement in disease

    Defects in CTSK are the cause of pycnodysostosis (PKND) [MIM:265800]. PKND is an autosomal recessive osteochondrodysplasia characterized by osteosclerosis and short stature.
  • Sequence similarities

    Belongs to the peptidase C1 family.
  • Cellular localization

    Lysosome.

  • Immunohistochemical analysis of paraffin-embedded human osteosarcoma tissue labeling Cathepsin K with ab207086 at 1/1000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.

    Cytoplasmic staining on osteoclasts of human osteosarcoma is observed [PMID: 17559135].

    Counter stained with Hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.

    Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
