NCIt definition : Cathepsin B (339 aa, 38 kDa) is encoded by the human CTSB gene. This protein plays
a role in proteolysis, immunity and the regulation of apoptosis.;
NCIt note : Cathepsin B is a lysosomal cysteine protease composed of a dimer of disulfide-linked
heavy and light chains, both produced from a single protein precursor.; Cathepsin B is also known as amyloid precursor protein secretase and is involved in
the proteolytic processing of amyloid precursor protein (APP). (Entrez Gene);
