说明

葫芦素E是一种有效的肌动蛋白解聚抑制剂。 葫芦素 E 比 jasplakinolide 更活跃,并且具有不同的作用机制,与不同的位点结合。 葫芦素 E 与丝状肌动蛋白 (F-肌动蛋白) 特异性结合,在 Cys257 残基处形成共价键,但不与单体肌动蛋白 (G-肌动蛋白) 结合,稳定 F-肌动蛋白,而不影响肌动蛋白聚合或成核。

一般描述

This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG.
 

生化/生理作用

Cucurbitacin E is a potent inhibitor of actin depolymerization. Cucurbitacin E is more active than jasplakinolide, and has a different mechanism of action, binding to a different site. Cucurbitacin E binds specifically to filamentous actin (F-actin) forming a covalent bond at residue Cys257, but not to monomeric actin (G-actin), stabilizing F-actin, without affecting actin polymerization or nucleation.
