Uses
α-Amanitin has been used:
- for inducing transcriptional arrest in NT2 cells prior to immunofluorescence assay
- to induce nephrotoxicity in mice renal tissues
- to induce and analyse genotoxicity in mice bone marrow cells by cell viability assay, comet assay and chromosomal aberration assay
Biological Activity
α-amanitin, the most deleterious toxin of a. phalloides to humans, inhibits rna polymerase ii (rnapii), causing hepatic and renal failure.
Biochem/physiol Actions
The major toxic constituent of the mushroom, Amanita phalloides, inhibits eukaryotic RNA polymerase II and III, but does not inhibit RNA polymerase I or bacterial RNA polymerase. Inhibits mammalian protein synthesis.
