Crotamine

Crotamine is a 42-residue polypeptide toxin from Crotalus durissus terrificus venom, stabilized by three disulfide bonds. It modulates voltage-gated sodium channels, interacts with cell membranes, and displays analgesic and myonecrotic activities, making it a valuable tool for neuropharmacology and pain research in both in vitro and in vivo studies.
