• Description: Actin disruption is used to study cell functions in vitro (e.g., migration, endocytosis) and in vivo (e.g., tumor cell invasion). Latrunculin A is a bioactive 2-thiazolidinone macrolide derived from sponges that sequesters G-actin and prevents F-actin assembly. It binds monomeric actin with 1:1 stoichiometry and can be used to block actin polymerization both in vitro (Kd = 0.2 μM) and in cells (0.5 μM, 30 min).{ Latrunculin A (1-10 μM) causes depolymerization of tumor cell cytoskeleton within ten minutes. Overnight treatment of cells with latrunculin A (10 μM) strongly suppresses actin synthesis. Prolonged cell treatment blocks dexamethasone-induced changes in actin cytoskeleton with no effect on cell viability.
• Uses: Latrunculin A has been used as medium supplementation for A549 cells to determine the internalization mechanism of CAV9 in A549 human lung carcinoma cells. Latrunculin A, Latrunculia magnifica is a stabilizer of monomeric G-actin and polymerization inhibitor.
