Toxin fs2
WebCalciseptine (CaS) is a natural neurotoxin isolated from the black mamba Dendroaspis p. polylepis venom. This toxin consists of 60 amino acids with four disulfide bonds. Calciseptine specifically blocks L-type calcium channels, but not other voltage -dependent Ca2+ channels such as N-type and T-type channels.

Calciseptine is a member of a family of toxic peptides found in snake venoms. Proteins from this family are small and consist of 58 to 74 amino acids. They all have the same three-fingered structure which arises from the formation of four disulfide bridges between eight cysteine residues. The activities of these toxins - although they are members of the same family - are actually quite …
