Function
Major toxin that belongs to the bicyclic heptapeptides called phallotoxins (PubMed:24613547). Although structurally related to amatoxins, phallotoxins have a different mode of action, which is the stabilization of F-actin (PubMed:24613547). Phallotoxins are poisonous when administered parenterally, but not orally because of poor absorption (PubMed:24613547).
