Application
(R)-MG132 has been used in ubiquitination assay and is used as a proteasome inhibitor.
Biochem/physiol Actions
MG132 (carbobenzoxy-Leu-Leu-leucinal) is a tri-peptide aldehyde. It possesses antitumor activity and boosts cytostatic/cytotoxic effects of chemo- and radiotherapy. (R)-MG132 is a potent, membrane-permeable proteasome inhibitor. It can inhibit proteasome activity in lysates of J558L multiple myeloma cells and EMT6 breast cancer cells. The (R)-MG132 stereoisomer is a more effective inhibitor of chymotrypsin-like (ChTL), trypsin-like (TL), and peptidylglutamyl peptide hydrolyzing proteasome (PGPH) activities than the (S)-MG132.

PIM1 is a proto-oncogene, encoding a serine/threonine protein kinase that regulates cell proliferation, survival, differentiation and apoptosis. Previous reports suggest that overexpression of PIM1 can induce cellular senescence. However, the molecular mechanism underlying this process is not fully understood. Here

Autophagy and the ubiquitin proteasome system (UPS), as two major protein degradation pathways, coordinate with each other in regulating programmed cell death. Autophagy can compensate for the UPS impairment-induced cell dysfunction and apoptosis. However, it is not clear how cells
