A 13-mer NMDA receptor 2B (NR2B) subunit carboxy terminal (1292-1304) derived peptide that specifically binds DAPK1 (death-associated protein kinase 1) in a reversible manner and antagonizes the activated DAPK1-NR2B interaction and the potentiation ofnMDAR function with no effect on either the catalytic activity of DAPK1 or thenMDA receptor physiology. Blocks Ca2+ influx through extrasynapticnMDA receptors (at 50uM) and the blood-brain-barrier permeable version, namely NR2BCT(1292-1304) attached to TAT(47-57) via a spacer (6-aminohexanoic acid) protects cortical neurons fromnMDA receptor-mediated insults and reduces brain infarction and improve neurological functions in mice (10mg/kg, i.v.).Sequence:H2N-Lys-Lys-Asn-Arg-Asn-Lys-Leu-Arg-Arg-Gln-His-Ser-Tyr-Ahx-Tyr-Gly-Arg-Lys-Lys-Arg-Arg-Gln-Arg-Arg-Arg-CONH2Formula:C143H254N64O32Molecular Weight:3382Solubility:DMSO (50mg/ml)Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
