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.

Latrunculin A is used extensively as an agent to sequester monomeric actin in living cells. We hypothesize that additional activities of latrunculin A may be important for its biological activity. Our data are consistent with the formation of a 1:1

Vesicle fusion is executed via formation of an Ω-shaped structure (Ω-profile), followed by closure (kiss-and-run) or merging of the Ω-profile into the plasma membrane (full fusion). Although Ω-profile closure limits release but recycles vesicles economically, Ω-profile merging facilitates release but

Immune cells exhibit stimulation-dependent traveling waves in the cortex, much faster than typical cortical actin waves. These waves reflect rhythmic assembly of both actin machinery and peripheral membrane proteins such as F-BAR domain-containing proteins. Combining theory and experiments, we develop
