Inhibition of actin polymerization by marine toxin pectenotoxin-2
Pectenotoxin-2 (PCTX-2) is one of the polyether macrolide toxins isolated from scallops involved in diarrheic shellfish poisoning via actin depolymerization. In the present study, we examined the bioactive mechanism of PCTX-2 in smooth muscle cells and clarify mode of action of the PCTX-2-induced actin depolymerization using purified skeletal actin. PCTX-2 (300 nM-3 µM) non-selectively inhibite...

متن کاملActin polymerization. The mechanism of action of cytochalasin D.
Fluorescence changes using actin covalently labeled with N-(1-pyrenyl)iodoacetamide have been used to determine the effect of cytochalasin D on actin polymerization. A mechanism for the effect of cytochalasin D on actin polymerization is presented, which explains the experimental observation of a cytochalasin D-induced increase in the initial rate of polymerization and a decrease in the final e...
متن کاملActin cytoskeleton: Putting a CAP on actin polymerization
Two recent studies have identified a Drosophila homolog of cyclase-associated protein (CAP) as a developmentally important negative regulator of actin polymerization that may also directly mediate signal transduction.
متن کاملPolymerization of ADP-actin
Using hexokinase, glucose, and ATP to vary reversibly the concentrations of ADP and ATP in solution and bound to Acanthamoeba actin, I measured the relative critical concentrations and elongation rate constants for ATP-actin and ADP-actin in 50 mM KCl, 1 mM MgCl2, 1 mM EGTA, 0.1 mM nucleotide, 0.1 mM CaCl2, 10 mM imidazole, pH 7. By both steady-state and elongation rate methods, the critical co...
