CC   -!- FUNCTION: Blocks olfactory (CNGA2) and retinal (CNGA1) CNG channel
CC       currents. Does not affect neither depolarization- nor caffeine-induced
CC       contraction of 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}.
