From Proteopedia
X-ray structure of crotamine, a cell-penetrating peptide from the Brazilian snake Crotalus durissus terrificus
Function
[MYXC_CRODU] This toxin specifically modifies voltage-gated sodium channels (Nav), it exhibits analgesic activity and causes severe muscle necrosis by a non-enzymatic mechanism. Moreover, it actively interacts with lipid membranes.[1] [2]
