Sleeper Peptide / N-methyl-D-Aspartate (NMDA) Receptor Antagonist

Conantokin G is a polypeptide originally isolated from the marine snail, Conus geographus. This synthetic 17 amino acid residue long peptide amide is an extremely active sleep inducing peptide (Sleeper Peptide) and a potent antagonist of N-methyl-D-aspartate (NMDA) receptor. Conantokin G is a structurally unusual peptide, because it contains a disproportionately large number of acid labile post-translational gamma-carboxyglutamic acid (Gla) residues.
