Name | Scorpion short toxin chloride channel inhibitor subfamily |
| Function | Short scorpion toxin chloride channel inhibitors are short-chain neurotoxins (SCNs), which block small-conductance chloride channels. They are 30-40-residue long and contain four intramolecular disulfide bridges, which have been assigned as C1-C4, C2-C6, C3-C7 and C5-C8. |
