Application
Clasto-乳胞素 β-内酯用作蛋白酶体抑制剂。
Clasto-乳胞素β-内酯已用作蛋白降解抑制剂以检测其对小鼠记忆改善的作用。它还用作人卵巢上皮(HOSE)细胞和树突状细胞(DC)的蛋白酶体抑制剂。
Biochem/physiol Actions
Clasto-乳胞素β-内酯(cLβL)由乳胞素(Lactacystin)合成。它具有细胞可透过性。cLβL可作用于蛋白酶体β -亚基X的N端苏氨酸。还可通过作用于β -型亚基的N-苏氨酸残基，抑制嗜盐古菌Haloferax volcanii的20S蛋白酶体活性。
细胞渗透性和不可逆蛋白酶体抑制剂。乳胞素作为染色体断裂-乳胞素 β 的前体-内酯。

Reactivated memory undergoes a rebuilding process that depends on de novo protein synthesis. This suggests that retrieval is dynamic and serves to incorporate new information into preexisting memories. However, little is known about whether or not protein degradation is involved

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

The natural product lactacystin exerts its cellular antiproliferative effects through a mechanism involving acylation and inhibition of the proteasome, a cytosolic proteinase complex that is an essential component of the ubiquitin-proteasome pathway for intracellular protein degradation. In vitro, lactacystin does

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

Protein degradation through the ubiquitin-proteasome system [UPS] plays a critical role in some forms of synaptic plasticity. However, its role in memory formation in the amygdala, a site critical for the formation of fear memories, currently remains unknown. Here we
