ω-conotoxin MVIIA, also knwn as Ziconotide acetate, is a peptide consisting of 25 amino acid.  It is a disulfide-bridged polypeptide from the venom of the sea snail Conusmagus that binds to neuronal N-type calcium channels. It forms a compact folded structure, presenting a loop between Cys8 and Cys15 that contains a set of residues critical for its binding. Both ω-conotoxins GVIA and MVIIA could bind to neuronal N-type calcium channels. ω-conotoxin GVIA is rich in hydroxyl groups while ω-conotoxin MVIIA contains a large number of positively charged side chains[1-2].

Ligand for binding studies of voltage sensitive calcium channels.

Prialt (Elan).

Neuronal N-type Ca2+ channel blocker in mammalian and amphibian brain; blocks release of GABA and glutamate at neuronal synapses.
