CC   -!- FUNCTION: Induces neurotoxic symptoms on zebrafish (By similarity). Has
CC       also been claimed to be implied in calcification, but tests on homolog
CC       proteins suggest that proteins of this family have a neurotoxic
CC       function and not a calcification function (PubMed:19283069).

CC   -!- SUBCELLULAR LOCATION: Secreted. Nematocyst {ECO:0000305}.
CC   -!- PTM: Contains 4 disulfide bonds. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the Cnidaria small cysteine-rich protein (SCRiP)
CC       family. {ECO:0000305}.
