Background: The Cystatin superfamily encompasses proteins that contain multiple Cystatin like sequences. Some of the members are active Cysteine protease inhibitors, while others have lost or perhaps never acquired this inhibitory activity. There are three inhibitory families in the superfamily, including the type 1 Cystatins (Stefins), type 2 Cystatins and Kininogens. Stefin B functions as an intracellular thiol protease inhibitor. The protein is able to form a dimer stabilized by noncovalent forces, inhibiting papain and cathepsins l, h and b. The protein is thought to play a role in protecting against the proteases leaking from lysosomes. Evidence indicates that mutated forms of this protein are responsible for the primary defects in patients with progressive myoclonic epilepsy.
