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 on
CC       smooth muscle (By similarity). {ECO:0000250|UniProtKB:Q8JI40}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:20203422}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC       {ECO:0000269|PubMed:20203422}.
CC   -!- PTM: Contains 8 disulfide bonds. {ECO:0000250|UniProtKB:P84808}.
CC   -!- SIMILARITY: Belongs to the CRISP family. {ECO:0000255}.
