CC -!- FUNCTION: Lethal toxin which possesses an inhibitory effect on direct
CC electrical stimulation of the isolated hemi-diaphragm of mice. Neither
CC hemorrhagic nor hemolytic activities are detected. Phospholipase A2
CC activity, proteolytic activity and arginine esterolytic activity are
CC absent (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed by the mandibular venom gland.
CC -!- SIMILARITY: Belongs to the beta-defensin family. Helofensin subfamily.
CC {ECO:0000305}.
