Cystatin B, also called stefin B or liver thiol proteinase inhibitor, is a member of family 1 of the cystatin superfamily (1). Like Cystatin A, it is an intracellular inhibitor regulating the activities of cysteine proteases of the papain family such as cathepsins B, H and L (2). Cystatin B-deficient mice have increased expression of proteolysis, apoptosis and glial activation genes, which is consistent with the pathology found in the mouse model of human progressive myoclonus epilepsy (EPM1) (3). The mouse Cystatin B consists of 98 amino acid residues (4).
