Cathepsin D Antibody [Biotin]

Cathepsin D is a lysosomal aspartic protease of the pepsin family (1). Human Cathepsin D is synthesized as a precursor protein, consisting of a signal peptide (residues 1‑18), a propeptide (residues 19-64), and a mature chain (residues 65‑412) (2‑4). The mature chain can be processed further to the light (residues 65‑161) and heavy (residues 169‑412) chains. It is expressed in most cells and overexpressed in breast cancer cells (5). It is a major enzyme in protein degradation in lysosomes, and also involved in the presentation of antigenic peptides. Mice deficient in this enzyme showed a progressive atrophy of the intestinal mucosa, a massive destruction of lymphoid organs, and a profound neuronal ceroid lipofucinosis, indicating that Cathepsin D is essential for proteolysis of proteins regulating cell growth and tissue homeostasis (6). Cathepsin D secreted from human prostate carcinoma cells are responsible for the generation of angiostatin, a potent endogeneous inhibitor of angiogenesis (6).
