CC -!- FUNCTION: Probably participates in a plant defense mechanism.
CC {ECO:0000255|PROSITE-ProRule:PRU00395}.
CC -!- DOMAIN: The presence of a 'disulfide through disulfide knot'
CC structurally defines this protein as a knottin. {ECO:0000305}.
CC -!- PTM: This is a cyclic peptide. {ECO:0000255|PROSITE-ProRule:PRU00395}.
CC -!- SIMILARITY: Belongs to the cyclotide family. Moebius subfamily.
CC {ECO:0000255|PROSITE-ProRule:PRU00395}.
CC -!- CAUTION: This peptide is cyclic. The start position was chosen by
CC similarity to Oak1 (kalata B1) for which the DNA sequence is known.
CC {ECO:0000255|PROSITE-ProRule:PRU00395}.
