NCIt definition : Cathepsin L1 (333 aa, 38 kDa) is encoded by the human CTSL gene. This protein is
involved in both proteolysis and immunity.;
NCIt note : Cathepsin L1 is a lysosomal cysteine protease composed of a dimer of disulfide-linked
heavy and light chains, both produced from a single protein precursor.; Cathepsin L1 substrates include collagen and elastin, as well as alpha-1 protease
inhibitor, a major controlling element of neutrophil elastase activity. (Entrez Gene);
