Background: Cathepsin H

Cathepsin H is a lysosomal cysteine protease of the papain family (1). It is synthesized as a precursor protein, consisting of a signal peptide (residues 1‑20), a propeptide (residues 21‑95), a mini chain (residues 96‑103), a heavy chain (residues 114‑290) and a light chain (residues 291‑333) (2, 3). A truncated form with a 12 amino acid deletion in the signal peptide region is secreted (4). Cathepsin H is the only known mono-aminopeptidase in the papain family (5). Cathepsin H expression is significantly increased in disease states such as in prostate tumors, sera of asthmatic patients, and mucosa of colorectal cancer patients (4, 6, 7).
