Target
-
FunctionClosely 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 specificityPredominantly expressed in osteclasts (bones).
-
Involvement in diseaseDefects in CTSK are the cause of pycnodysostosis (PKND) [MIM:265800]. PKND is an autosomal recessive osteochondrodysplasia characterized by osteosclerosis and short stature.
-
Sequence similaritiesBelongs to the peptidase C1 family.
-
Cellular localizationLysosome.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Cathepsin K antibody (ab19027)This image is a courtesy of Anonymous Abreviewab19027 staining Cathepsin K in mouse bone tissue section, in which human MDA-MB-231 Breast Cancer cells were grown, by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue underwent paraformaldehyde fixation and then blocking with 10% Casein for 30 minutes at 22°C was performed. The primary antibody was diluted 1/200 and incubated with sample in 10% Casein for 17 hours at 4°C. A Biotin conjugated goat polyclonal to rabbit IgG was used as secondary antibody at 1/200 dilution.

Immunocytochemistry/ Immunofluorescence - Anti-Cathepsin K antibody (ab19027)This image is courtesy of an Abreview submitted by Alina Macoveiab19027 staining Cathepsin K in the Human cell line HepaRG by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with formaldehyde, permeabilized with Triton X-100 0.1% and blocked with 1% milk for 30 minutes at 21°C. Samples were incubated with primary antibody (1ug/ml in 1% milk) for 30 minutes. An Alexa Fluor®594-conjugated Goat anti-rabbit IgG polyclonal(1/400) was used as the secondary antibody. -
Immunohistochemistry (Frozen sections) - Anti-Cathepsin K antibody (ab19027)Image courtesy of an anonymous Abreview.ab19027 staining Cathepsin K in rat osteoclasts by Immunohistochemistry (Frozen sections). 21 day old rat bone was fixed in methanol and then blocked using 20% serum for 30 minutes at 22°C. Samples were then incubated with primary antibody at 1/50 for 3 hours at 22°C. The secondary antibody used was an anti-rabbit IgG conjugated to Cy3® (red) used at a 1/1000 dilution. -
