Description

General description

Latrunculin A, a toxin extracted from the red sea sponge Latrunculia magnifica. It participates in vitro in the morphological alteration of the polymerization of pure actin. It forms a complex by binding with the nucleotide cleft of actin for actin filaments elongation.

Application

Latrunculin A has been used as medium supplementation for A549 cells to determine the internalization mechanism of CAV9 in A549 human lung carcinoma cells.

Biochem/physiol Actions

Latrunculin A inhibits actin polymerization by a different mechanism than cytochalasins. Latrunculin A disrupts microfilament-mediated processes.
