CC   -!- FUNCTION: Does not show antimicrobial, myotoxic, hemolytic and cell-
CC       promoting activities. {ECO:0000269|PubMed:10417345}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:10417345}.
CC   -!- TISSUE SPECIFICITY: Produced by the crural gland and detected in venom
CC       from the spur located on each male hind leg. Is also widely expressed
CC       in both male and female tissues, including intestine, kidney, spleen
CC       and testis. {ECO:0000269|PubMed:10417345, ECO:0000269|PubMed:18662710}.
