Probably participates in a plant defense mechanism (Probable). Has no activity against bacteria up to a concentration of 80 uM (PubMed:22467870). Has cytotoxic but no hemolytic activity (PubMed:22467870). The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin. This is a cyclic peptide. Belongs to the cyclotide family. Bracelet subfamily. This peptide is cyclic. The start position was chosen by similarity to chassatide C4 for which the DNA sequence is known.
