CTSL Human Recombinant produced in E. Coli is a single,non-glycosylated polypeptide chain containing 339 amino acids (18-333 a.a) andhaving a molecular mass of 38.3kDa. CTSL is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Cathepsin-L also known as CTSL is a member of the peptidase C1 family. CTSL, is a dimer composed of disulfide-linked heavy and light chains, bothformed from a single protein precursor. Furthermore, CTSL is a lysosomalcysteine proteinase which takes a main part in intracellular proteincatabolism. CTSL substrates include collagen and elastin, as well as alpha-1protease inhibitor, which is the most important controlling element ofneutrophil elastase activity. CTSL has been implicated in a number of pathologicprocesses, including myofibril necrosis in myopathies and in myocardialischemia, and in the renal tubular response to proteinuria. Multiplealternatively spliced transcript variants have been found for CTSL.
