This recombinant protein induces severe neurotoxicity on zebrafish larvae (Danio rerio) at a concentration of 230 mg/ml, but does not show toxicity when injected in blowfly larvae (Sarcophaga falculata). All fish incubated with this protein died within 200 minutes of exposure (PubMed:25757852). Has also been claimed to be implied in calcification, but this function seems improbable (PubMed:19283069, PubMed:25757852). Contains 4 disulfide bonds. The sequence shown here is derived from an EMBL/GenBank/DDBJ third party annotation (TPA) entry. Belongs to the Cnidaria small cysteine-rich protein (SCRiP) family.
