Background: Cystatin A

Cystatin A, also called stefin A, Cystatin AS or keratolinin, is a member of family 1 of the cystatin superfamily (1, 2). Like Cystatin B, it is an intracellular inhibitor regulating the activities of cysteine proteases of the papain family such as cathepsins B, H and L (3). For example, immunohistochemical analysis of Cystatin A and cathepsin L is a useful indicator for malignancy in human epidermal keratinocytes (4). The ratio of cathepsin B and Cystatin A can be used in the differential diagnosis and treatment of patients with prostate carcinoma (5). The human Cystatin A consists of 98 amino acids (1).
