Cathepsin D is a protein that in humans is encoded by the CTSD gene.[1][2]

This gene encodes a lysosomal aspartyl protease composed of a protein dimer of disulfide-linked heavy and light chains, both produced from a single protein precursor. This proteinase, which is a member of the peptidase A1 family, has a specificity similar to but narrower than that of pepsin A. Transcription of this gene is initiated from several sites, including one that is a start site for an estrogen-regulated transcript. Mutations in this gene are involved in the pathogenesis of several diseases, including breast cancer and possibly Alzheimer disease.[2]

It has been used as a breast cancer tumor marker.[3]

Cathepsin-D is an aspartic protease that depends critically on protonation of its active site Asp residue and gets activated at pH 5 in endosome of hepatocytes where it degrades insulin. Along with Asp-protonation, lower pH also leads to conformational switch in cathepsin-D : the N terminal segment of the protease moves out of the active site as pH drops. [4] [5] [6] Ceramide binds-to and activates cathepsin D.[7]
