Background: Cystatin F

Cystatin F, also known as leukocystatin and CMAP (Cystatin-like Metastasis-Associated Protein), is a member of the cystatin superfamily (1‑3). Cystatin F is selectively expressed by hematopoietic cells and may be a biomarker for both liver metastasis and inflammatory lung disorders (3, 4). As a cysteine protease inhibitor, it shows selectivity towards cathepsin L and legumain (1, 2, 5). Compared to other secreted cystatins including C, D, E/M, S, SA and SN, which contain two intra disulfide bonds, cystatin F has two extra Cys residues that may be involved in inter disulfide bonds. Indeed, rhCystatin F showed disulfide bond-linked dimer formation, which was also the case for an E. coli expressed fusion protein containing mature human cystatin F and glutathione S-transferase (2).
