CC   -!- FUNCTION: Has low cytotoxic activity. {ECO:0000250|UniProtKB:P14541}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P62375}. Target
CC       cell membrane {ECO:0000250|UniProtKB:P62375}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland. {ECO:0000305}.
CC   -!- MISCELLANEOUS: Is classified as a P-type cytotoxin, since a proline
CC       residue stands at position 52 (Pro-31 in standard classification).
CC       {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the snake three-finger toxin family. Short-chain
CC       subfamily. Orphan group XV sub-subfamily. {ECO:0000305}.
