Alternate Names for Cystatin B/Stefin B Antibody [Unconjugated]
CST6cystatin B (liver thiol proteinase inhibitor)10STFBcystatin-B
cystatin B (stefin B)
Liver thiol proteinase inhibitor
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). Mutations in the Cystatin B gene is the cause of progressive myoclonus epilepsy (EPM1) (3). Because of its expression patterns, Cystatin B can be used as a marker for certain cancers, such as glioblastoma tumors (4). It readily forms amyloid fibrils in vitro (5). The human Cystatin B consists of 98 amino acid residues (3).
