Has low cytotoxic activity. Expressed by the venom gland. LD(50) is 6.25 mg/kg by intravenous injection. These two sequences have Gly and Leu at positions 25 and 27, respectively, instead of 2 Met that are found in most cytotoxins. The low toxicity of these 2 proteins may possibly be correlated with these changes. Is classified as a P-type cytotoxin, since a proline residue stands at position 30 (Pro-31 in standard classification). Belongs to the snake three-finger toxin family. Short-chain subfamily. Orphan group XV sub-subfamily.
