Mambalgin 1 Chemical Properties,Usage,Production

Uses

Mambalgin-1 is a toxin isolated from black mamba venom. Mambalgin-1 is a disulfide-rich polypeptide consisting of 57 amino acids and belongs to the family of three-finger toxins. Mambalgin-1 can bind to and stabilize ASICs (acid-sensing ion channels) in a physiologically relevant closed-channel conformation[1].
