CC   -!- FUNCTION: Interferes with one step of hemostasis (modulation of
CC       platelet aggregation, or coagulation cascade, for example).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Heterodimer; disulfide-linked. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC   -!- MISCELLANEOUS: Shows greater sequence similarity to the beta than alpha
CC       subunits compared to other heterodimer snaclecs.
CC   -!- SIMILARITY: Belongs to the snaclec family. {ECO:0000305}.
