Definition of phalloidin in English: phalloidinnoun faˈlɔɪdɪn mass nounChemistry 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. Example sentencesExamples - 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.
- 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.
- Actin was localized using rhodamine-conjugated phalloidin.
- Egg chambers were stained with Alexa 488-labeled phalloidin to reveal actin-rich structures (blue).
Origin 1930s: from modern Latin phalloides, specific epithet of the death cap toadstool Amanita phalloides (based on Greek phallos 'phallus') + -in1. |
