LACTACYSTIN Chemical Properties,Uses,Production

Description

Lactacystin is a microbial metabolite isolated from Streptomyces that is now widely used as a selective inhibitor of the 20S proteasome. Lactacystin was first characterized by its ability to induce differentiation and inhibit cell cycle progression in several tumor cell lines. At concentrations from 2 to 10 μM, lactacystin induces the outgrowth of neurites in the neuroblastoma cell line Neuro2a. Lactacystin irreversibly alkylates subunit X of the 20S proteasome. The concomitant inhibition of proteasome peptidase activity results in the accumulation of a variety of ubiquitinated proteins which would normally undergo rapid degradation. Thus, the effects of lactacystin are pleiotropic and depend substantially on the expression pattern of signalling proteins within the treated cell.

Chemical Properties

White Powder

Uses

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

Definition

ChEBI: L-Cysteine substituted at nitrogen by an acetyl group and at sulfur by a substituted-lactam carbonyl group.

General Description

Lactacystin is an antibiotic?and a metabolite of Streptomyces?spp.
