Robin is a lectin, a carbohydrate-binding protein, and a highly potent toxin.[1] Robin is a type of toxalbumin.
Robin as a natural toxalbumin, is an intricate protein encountered in specific plant species, and exhibits toxicity upon ingestion, inhalation, or parenteral administration. Predominant sources of robin include the species Ricinus communis and Robinia pseudoacacia and is distributed across the wood, bark, seeds, leaves, and roots. It belongs to toxalbumins, along with ricin and abrin. These toxins are categorized as ribosome-inactivating proteins (RIP).
Robin can have fatal action, or result in necrosis.[2]
