Product Description
Highly specific, cell permeable, and irreversible 20S proteasome inhibitor. Inhibits ubiquitin proteasome pathway in cell culture (IC50=1µM). It has been suggested that the natural product lactacystin acts as a precursor for clasto-lactacystin β-lactone and that the latter is the sole species that interacts with the proteasome. Inhibits cathepsin A. Leads to a reduction of adipogenesis.

General Information
Cathepsin L [EC 3.4.22.15] is a lysosomal endopeptidase belonging to the papain family of the closely related cysteine proteases superfamily. The enzyme is ubiquitously distributed in the lysosomes of all cells and seems to be involved in a variety of disorders in which the pathological destruction of the extracellular matrix is one of the main characteristics.
