General description

A potent, reversible, and cell-permeable proteasome inhibitor (Ki = 4 nM). Reduces the degradation of ubiquitin-conjugated proteins in mammalian cells and permeable strains of yeast by the 26S complex without affecting its ATPase or isopeptidase activities. Activates c-Jun N-terminal kinase (JNK1), which initiates apoptosis. Inhibits NF-κB activation (IC50 = 3 µM). Also reported to increases the survival rate of mesenchymal stem cells following their transplantation. Prevents β-secretase cleavage. A 10 mM (1 mg/210 µl) solution of MG-132 (Cat. No. 474791) in DMSO is also available. This material is ≥98% pure by HPLC. A material with ≥95% purity by HPLC (Cat. No. 474787) is also available.

Biochem/physiol Actions

Cell permeable: yes
Primary Target
proteasome
Product does not compete with ATP.
Reversible: yes
Target IC50: 3 µM against NF-κB activation
Target Ki: 4 nM against proteasome

Preparation Note

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 1 month at -20°C.
