Probably participates in a plant defense mechanism (Probable). Has insecticidal activity against H.armigera larvae (PubMed:28006906). 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. Moebius subfamily. This peptide is cyclic. The start position was chosen by similarity to Oak1 (kalata B1) for which the DNA sequence is known.
