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. WebJul 20, 2012 · The actin–cofilin interaction is also negatively regulated upon binding of phosphoinositides, such as phosphatidylinositol 4,5-bisphosphate (PIP2), to cofilin [10], and upon binding of actin-binding proteins, such as profilin and tropomyosin, to G- or F-actin [11], [12], [13].
