General description
Cystatin B is a member of the type 1 (stefins) superfamily of cystatins. Cystatin B is encoded by the CSTB gene and functions as an intracellular thiol protease inhibitor regulating the activity of members of the papain family and cathepsins B, H, and L. Cystatin B may also protect cellular components from the effects of proteases that leak from lysosomes. Mutations in the CSTB gene are thought to be the primary defect in patients with Progressive Myoclonus Epilepsy (EPM1).
Application
Suitable for use as a cysteine-protease inhibitor. Is tested for suitability as an inhibitor of the enzymatic activity of papain.
Biochem/physiol Actions
Cystatin B was shown to interact with the protein RACK-1, β-spectrin and neurofilament light chain NF-L forming a unique multiprotein complex specifically in the cerebellum, confirming its function in the brain. [1]
Preparation Note
Cystatin B should be reconstituted at 100 μg/mL in steile 25 mM Tris pH 7.5 and 100 mM NaCl. Reconstituted product should be stored in single-use aliquots at -70° C and should be stable for at least 3 months.

Cystatin B is an anti-proteolytic polypeptide implicated in progressive myoclonus epilepsy (EPM1), a degenerative disease of the central nervous system. The knock-out mouse model of the disease shows apoptosis of the cerebellar granule cells. We have identified five recombinant proteins

Schistosomula (the post-infective stages) of the neurotropic schistosome Trichobilharzia regenti possess multiple isoforms of cathepsin B1 peptidase (TrCB1.1-TrCB1.6) with involvement in nutrient digestion. The comparison of substrate preferences of TrCB1.1 and TrCB1.4 showed that TrCB1.4 had a very narrow substrate

Severed axon tips reform growth cones following spinal cord injury that fail to regenerate, in part, because they become embedded within an inhibitory extracellular matrix. Chondroitin sulfate proteoglycans (CSPGs) are the major axon inhibitory matrix component that is increased within
