ⓘ Latrunculin

The latrunculins are a family of natural products and toxins produced by certain sponges, including genus Latrunculia and Negombata, whence the name is derived. It binds actin monomers near the nucleotide binding cleft with 1:1 stoichiometry and prevents them from polymerizing. Administered in vivo, this effect results in disruption of the actin filaments of the cytoskeleton, and allows visualization of the corresponding changes made to the cellular processes. This property is similar to that of cytochalasin, but has a narrow effective concentration range. Latrunculin has been used to great effect in the discovery of cadherin distribution regulation and has potential medical applications. Latrunculin A, a type of the toxin, was found to be able to make reversible morphological changes to mammalian cells by disrupting the actin network.

Latrunculin A:

Objectives and functions

Gelsolin - Latrunculin a causes a lock, this protein binds to the barbed side of actin filaments, which accelerate nucleation. This calcium-regulated protein also plays a role in the Assembly and disassembly of cilia, which plays a crucial role in objectivity.

Latrunculin B:

Objectives and functions

Actin - Latrunculin B is the structure of actin fibers.

The protein spire homolog 2 - required for cell division, transport of vesicles in the actin filament and is essential for the formation of the formation of cleavage during cell division.
