生物活性
Jasplakinolide is an actin-specific reagent that promotes actin polymerization and stabilizes actin filaments.In vitro, Jasplakinolidet potently induces actin polymerization by stimulating actin filament nucleation and competes with phalloidin for actin binding (Kd = 15 nM).In vivo, Jasplakinolide has been found to disrupt actin filaments and induce polymerization of monomeric actin into amorphous masses, the exact mechanism of which has not been determined yet. Jasplakinolide differs from other actin stabilizers in that it is cell permeable. This peptide has fungicidal, insecticidal and antiproliferative activity, and is useful for investigating cell processes mediated by actin polymerization and depolymerization, such as cell adhesion, locomotion, endocytosis, and vesicle sorting and release.
