    • Function

    • Cationic peptide that possess multiple functions. It acts as a cell-penetrating peptide (CPP), and as a potent voltage- gated potassium channel (Kv) inhibitor. It exhibits antimicrobial activities, hind limb paralysis, and severe muscle necrosis by a non-enzymatic mechanism (By similarity).
    • Tissue specificity

    • Expressed by the venom gland.
