General description

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 of NMDAR function with no effect on either the catalytic activity of DAPK1 or the NMDA receptor physiology. Blocks Ca²⁺ influx through extrasynaptic NMDA receptors (at 50 µM) and the blood-brain-barrier permeable version, namely NR2B_CT(1292-1304) attached to TAT(47-57) via a spacer (6-aminohexanoic acid) protects cortical neurons from NMDA receptor-mediated insults and reduces brain infarction and improve neurological functions in mice (10 mg/kg, i.v.).
