Latrunculin mechanism of action
WebThe study aimed to elucidate the binding mode of Latrunculin A, naturally occurring analogue Latrunculin B and a synthetic analogue L32 computationally to G actin. The … Latrunculin A and latrunculin B affect polymerization of actin. Latrunculin binds actin monomers near the nucleotide binding cleft with 1:1 stoichiometry and prevents them from polymerizing. The nucleotide monomers are prevented from dissociation from the nucleotide binding cleft, thus preventing … Meer weergeven 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 … Meer weergeven Yeast cells in absence of the proteins osh3 or osh5 demonstrated hypersensitivity to latrunculin B. The osh proteins are … Meer weergeven In nature, latrunculins are used by the sponges themselves as a defense mechanism, and for the same purpose are also sequestered by certain nudibranchs. Latrunculins are produced for fundamental research and have potential medical applications … Meer weergeven Latrunculin is a toxin that is produced by sponges. The red-coloured Latrunculia Magnifica Keller is an abundant sponge in the Meer weergeven There are several isomers of latrunculin, A, B, C, D, G, H, M, S and T. The most common structures are latrunculin A and B. Their formulas are respectively C22H31NO5S … Meer weergeven As latrunculin inhibits actin polymerization and actomyosin contractile ability, exposure to latrunculin may result in cellular relaxation, expansion of drainage tissues and decreased outflow resistance in e.g. the trabecular meshwork.
