CC -!- FUNCTION: Weakly 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}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC -!- SIMILARITY: Belongs to the CRISP family. {ECO:0000305}.
