Cystatin B (CSTB) is a type 1 cystatin belonging to the cystatin superfamily. There are three cystatin subfamilies including type 1 cystatins, type 2 cystatins, and kininogens. Cystatins are thought to have a protective role against the proteases that leak from the lysosomes by inhibiting their cysteine proteinase activity. CSTB can covalently form dimers, tetramers, or oligomers. CSTB oligomers bind to aggregated amyloid-beta (Aβ) and reduce Aβ fibril formation.
