Popis

General description

Lactacystin is an antibiotic and a metabolite of Streptomyces spp.

Application

Lactacystin has been used:

• as a proteasome inhibitor to inhibit protein degradation
• to inhibit proteasomal activity of cells for live cell imaging
• to block proteasomal proteolysis in human monocyte-derived dendritic cells (MoDCs) for 24 h
• to provide unilateral injection to animals to induce nigrostriatal lesions

Biochem/physiol Actions

Lactacystin can block the development of cell cycle and stimulate differentiation in a murine neuroblastoma cell line. It can serve as a precursor for clasto-lactacystin β-lactone. Cell-permeable and irreversible proteasome inhibitor (Ki = 4nM). Inhibits NF-kB activation (IC50 = 10mM). Induces neurite outgrowth in neuro2A mouse neuroblastoma cells.
