| Application【应用】 | Cucurbitacin E has been used as a cofilin inhibitor. It is also used as a F-actin stabilizer to prevent membrane-associated periodic skeleton (MPS) loss and protect from axonal fragmentation. |
| Biochem/physiol Actions【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. |
