Application

Clasto-Lactacystin β-lactone has been used as a proteasomal inhibitor.
Clasto-Lactacystin β-lactone has been used as a protein degradation inhibitor to test its effect on memory improvements in mice. It has also been used as a proteasome inhibitor in human ovarian surface epithelium (HOSE) cells and dendritic cells (DCs).

Actions biochimiques/physiologiques

Cell-permeable and irreversible proteasome inhibitor. Lactacystin acts as a precursor for clasto-lactacystin β-lactone.
Clasto-Lactacystin β-lactone (cLβL) is synthesized from lactacystin. It is cell-permeable and cLβL acts on the N-terminal threonine of subunit proteasome β -subunit X It also inhibits 20S proteasome activity in Haloferax volcanii by acting in the N-threonine residue of the  β -type subunits.

Intracellular trafficking of viral movement proteins (MPs) in plants has mainly been studied using Tobacco mosaic virus MP30 (TMV MP30) as a model system. Because of the limitations of TMV MP30 expression in Arabidopsis thaliana, these studies have mostly been

The ubiquitin proteasome system, generally known for its function in protein degradation, also appears to play an important role in regulating membrane trafficking. A role for the proteasome in regulating presynaptic release and vesicle trafficking has been proposed for invertebrates

The antibiotic lactacystin was reported to covalently modify beta-subunit X of the mammalian 20 S proteasome and inhibit several of its peptidase activities. However, we demonstrate that [3H]lactacystin treatment modifies all the proteasome's catalytic beta-subunits. Lactacystin and its more potent

In this study, we investigated the role of two inducible repressor proteins, inducible cAMP early repressor (ICER) and Fos-related antigen 2 (Fra-2) in the adrenergic induction of MAPK phosphatase-1 (MKP-1) as compared with their roles in the induction of arylalkylamine-N-acetyltransferase
