CC   -!- FUNCTION: Blocks contraction of smooth muscle elicited by high
CC       potassium-induced depolarization, but does not block caffeine-
CC       stimulated contraction. May target voltage-gated calcium channels in
CC       smooth muscle (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC   -!- SIMILARITY: Belongs to the CRISP family. {ECO:0000305}.
