CC   -!- FUNCTION: Venom component which lacks hemolytic or antibiotic
CC       properties, but produces an inflammatory response via mast cell
CC       degranulation and produces a chemotactic effect on leukocytes.

CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:15572194}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
