Cathepsin D, a lysosomal aspartic protease, belongs to the pepsin family. Mouse Cathepsin D consists of a signal peptide (residues 120), a propeptide (residues 2164), and a mature chain (residues 65410) (13). Cathepsin D is expressed in most cells and overexpressed in in some cancer (breast, melanoma, ovary, etc.). Cathepsin D increases the incidence of clinical metastasis involves increased cell growth and decreased contact inhibition rather than escape of cancer cells through the basement membrane[1][2].
Cathepsin D acts as a protease following its activation at an acidic pH, or as a ligand of different membrane receptors at a more neutral pH[1].
