The toxin present in the death cap toadstool. It is a peptide with seven amino acids in a ring structure bridged by a sulphur atom.
- We show here that photosensitization with BAYy 3118 induces an immediate loss of actin reactivity with phalloidin, a toxin that specifically forms tight complexes with polymerized F - actin.
- However, since phalloidin stabilizes F-actin structure and virtually abolishes the dissociation of actin monomers from filament ends, it also inhibits the dynamic behavior of actin filaments.
- Egg chambers were stained with Alexa 488-labeled phalloidin to reveal actin-rich structures (blue).
