Probably participates in a plant defense mechanism. Expressed in midvein, lamina and periphery of leaves (at protein level). The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin. Contains 3 disulfide bonds. Belongs to the cyclotide family. Bracelet subfamily. This peptide is linear but closely related to cyclotides. Since in UniProtKB the primary structure is preferred to classify proteins, the sequence is assigned to the cyclotide family.
