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

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

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

Latrunculin A, a toxin purified from the red sea sponge Latrunculia magnifica, was found previously to induce striking reversible changes in the morphology of mammalian cells in culture and to disrupt the organization of their microfilaments. We now provide evidence

Dynamin GTPases, best known for their role in membrane fission of endocytic vesicles, provide a target for viruses to be exploited during endocytic uptake. Recently, we found that entry of herpes simplex virus 1 (HSV-1) into skin cells depends on
