Probably participates in a plant defense mechanism (Probable). Active against E.coli ATTC25922 but not against S.aureus ATCC 12600 or S.epidermidis ATCC 14990 (PubMed:22467870). Has cytotoxic and hemolytic activity (PubMed:22467870). Expressed in fruit, pedicel, root and stem but not in leaf (at protein level). The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin. Belongs to the cyclotide family. Bracelet subfamily. The mature peptide is linear as it lacks the C-terminal Asp/Asn residue required for cyclization.
