일반 설명
Phalloidin is a phallotoxin produced by death cap mushroom Amanita phalloides. It is a cyclic peptide, which interacts with actin, and this was first identified in phalloidin-poisoned rats. It is a heptapeptide, cyclic in nature, with a crosslink between tryptophan at position 6 and cysteine at position 3. The side chain of amino acid 7 (γ-δ-dihydroxyleucine) in phalloidin, is accessible to modifications, through which florescent labelled phalloidin compounds can be produced.
애플리케이션
Fluorescent phallotoxin which may be used to identify filamentous actin.
Phalloidin-Tetramethylrhodamine B isothiocyanate has been used:-
Phalloidin-Tetramethylrhodamine B isothiocyanate has been used:-
- In Immunofluorescence for staining Filamentous actin (F-actin)
- To stain cells during immunocytochemical and cytochemical analysis
- To label actin microfilaments for fluorescence microscopy
생화학적/생리학적 작용
Phalloidin interacts with polymeric actin, and not oligomeric or monomeric forms. This interaction leads to highly stabilized actin filaments, which resist depolymerization and disassembly. In rats, this toxin causes death due to liver hemorrhage, and cells show abnormal actin clustering. The affinity of phalloidin to actin is not significantly altered after derivatizing florescent labelled phalloidin compounds. These compounds can be used to study actin structure and organization within eukaryotic cells.
Toxin that binds polymeric F actin, stabilizing it and interfering with the function of actin-rich structures.

Perineuronal nets (PNNs) are condensed structures in the extracellular matrix that mainly surround GABA-ergic parvalbumin-positive interneurons in the adult brain. Previous studies revealed a parallel between PNN formation and the closure of the critical period. Moreover, ocular dominance plasticity is

Macrophage migration into injured or infected tissue is a key aspect in the pathophysiology of many diseases where inflammation is a driving factor. Membrane-type-1 matrix metalloproteinase (MT1-MMP) cleaves extracellular matrix components to facilitate invasion. Here we show that, unlike the

Pseudopodia are actin-rich ventral protrusions associated with cell motility and cancer cell invasion. We previously applied our established method of using excimer laser cell etching to isolate pseudopodial proteins from MDA-MB-231 breast cancer cells. We later identified 14-3-3γ as an

A fluorescent derivative of phalloidin has been synthesized possessing high affinity to filamentous actin. This compound was used for visualization of actin-containing structures in eukaryotic nonmuscle cells. Due to its low molecular weight (1250), fixation for formaldehyde was sufficient to
