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.
‘Actin was localized using rhodamine-conjugated phalloidin.’
‘Egg chambers were stained with Alexa 488-labeled phalloidin to reveal actin-rich structures (blue).’
‘In a double-labeled red cell with rhodamine phalloidin and F1 - PE, the lipid pattern is again accompanied by a weaker, dim but observable perturbation of the actin distribution.’
‘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.’
‘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.’
Origin
1930s: from modern Latin phalloides, specific epithet of the death cap toadstool Amanita phalloides (based on Greek phallos ‘phallus’) + -in.
