Amino Acid Sequence
Cys-Lys-Ser-Hyp-Gly-Ser-Ser-Cys-Ser-Hyp-Thr-Ser-Tyr-Asn-Cys-Cys-Arg-Ser-Cys-Asn-Hyp-Tyr-Thr-Lys-Arg-Cys-Tyr-NH2 [Disulfide Bridges: 1-16, 8-19, 15-26]
Application
ω-Conotoxin GVIA has been used as an antagonist for N-type calcium channel (CaV2.2) in various studies.
Powerful probe for exploring the vertebrate pre-synaptic terminal.
Biochem/physiol Actions
ω-Conotoxin GVIA is a 27 amino acid neurotoxin containing three disulfide bonds. It inhibits central neurotransmitter release and also exhibits antihypertensive, analgesic and neuroprotective activities.
Blocks specific voltage-dependent N-type Ca2+ channels in neurons, but not in muscle; does not bind to either the dihydropyridine or verapamil binding sites; peptide first isolated from the marine snail Conus geographus L.
