Cytochalasin actin
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. WebMay 23, 2000 · Latrunculins bind to G-actin in a 1:1 molar complex, thereby limiting the availability of actin monomers for polymerizing at either barbed or pointed ends of actin filaments . The cytochalasins have multiple complex effects on actin in vitro ; however, at low concentrations, their primary effect in cells is to cap the barbed ends of actin ...
