Biomarker: cathepsin D

Histology type: endometrial carcinoma

Country: Germany

Followed up time :

Conclusion: The prognostic value of cathepsin D in endometrial carcinoma.The overexpression of Cathepsin D seems to be important for exact biologic characterization of each endometrial carcinoma with respect to local proteolytic activity. The enhanced activity of cathepsin D may therefore serve as an additional objective malignancy criterion independent of the well-known prognostic factors.

Sample type : tissue

Sample method: RIA

Expression pattern : overexpression

Funtion Uniprot: Acid protease active in intracellular protein breakdown. Plays a role in APP processing following cleavage and activation by ADAM30 which leads to APP degradation (PubMed:27333034). Involved in the pathogenesis of several diseases such as breast cancer and possibly Alzheimer disease

UniProt ID: P07339

Molecular function from UniProt:

Tissue specificity from UniProt: Expressed in the aorta extracellular space (at protein level) (PubMed:20551380). Expressed in liver (at protein level) (PubMed:1426530).

Subcellular UniProt: #Lysosome #Secreted

Cleaved: Cleaved into 2 chains Cathepsin D light chain Cathepsin D heavy chain

Catalytic activity: Specificity similar to, but narrower than, that of pepsin A. Does not cleave the 4-Gln-|-His-5 bond in B chain of insulin.
