Function
Major toxin that belongs to the bicyclic heptapeptides called phallotoxins (PubMed:18025465). Although structurally related to amatoxins, phallotoxins have a different mode of action, which is the stabilization of F-actin (PubMed:18025465). Phallotoxins are poisonous when administered parenterally, but not orally because of poor absorption (PubMed:18025465).
