Cytochalasin actin
WebActin, however, is involved in the further constriction of the cleavage furrow in the second phase of cytokinesis and in the morphogenesis of the theca. In the presence of cytochalasin D, dinoflagellates undergo mitosis and the cells begin to divide, but the completion of cell division is inhibited. WebCytochalasin D is a cell-permeable mycotoxin that binds to the barbed end of actin filaments inhibiting both the association and dissociation of subunits. It causes the disruption of actin filaments and inhibition of actin polymerization. As a result, it impedes with a variety of processes including cell cycle, motility, phagocytosis ...

WebDec 1, 2009 · Actin crosslinking toxins produced by Gram-negative bacteria represent a small but unique class of bacterial protein toxins. For each of these toxins, a discrete actin crosslinking domain (ACD) that is a distant member of the ATP-dependent glutamine synthetase family of protein ligases is translocated to the eukaryotic cell cytosol. This … WebIn 0.5 mM MgCl2, cytochalasin D uncoupled the actin ATPase activity from actin polymerization, increasing the ATPase rate by at least 20 times while inhibiting …
WebCytochalasins comprise a group of about 20 known compounds derived from molds, which affect actin stress fibers, causing rapid actin depolymerization. Cytochalasins bind to the growing end of F-actin, inhibit polymerization without affecting depolymerization, and cause disassembly of actin fibers. WebOur candidate tumor suppressor p38 as well as its downstream targets such as phosphorylation of mTOR, actin remodeling and autophagy can be modulated with pharmacologically available small molecules such as anisomycin, rapamycin, hydroxychloroquine and cytochalasin.
WebFilopodial actin bundles guide microtubule assembly in the growth cone peripheral (P) domain and retrograde actin-network flow simultaneously transports microtubules rearward. Therefore, microtubule-end position is determined by the sum of microtubule assembly and retrograde transport rates. ... Cytochalasin B / pharmacology Growth Cones ... WebA dynamic actin cytoskeleton is essential for pollen germination and tube growth. However, the molecular mechanisms underlying the organization and turnover of the actin cytoskeleton in pollen remain poorly understood.
Web6.4 Association of F-actin cortex with ion channels involved in exocytosis. A number of studies suggest that actin filaments may modulate the activity of a range of ion channels. For example, cytochalasin D alters the ion flux associated with calcium channels (Johnson and Byerly, 1993) and voltage-dependent sodium channels (Cantiello et al., 1991).
