Phallacidin is a natural bicyclic heptapeptide derived from the poisonous mushroom Amanita phalloides. Phallacidin binds to filamentous actin specifically with high affinity, with a Kd of 20 nM. After binding to F-actin, Phallacidin strongly inhibits its depolymerization, stabilizes microfilament structures, and prevents their disruption by drugs such as cytochalasins. When conjugated with a fluorophore, Phallacidin serves as a specific fluorescent probe for F-actin, which is used to clearly visualize the distribution of actin in the cytoskeleton (e.g., stress fibers, cortical peripheral bands) under fluorescence microscopy .
