Background
Ephrin-B2 binding to its receptor EphB leads to the activation of Src family tyrosine kinases, which phosphorylate NMDAR2B at Tyr1252, Tyr1336, and Tyr1472. In turn, phosphorylated NMDAR2B enhances the ability of the functional NMDA receptor to regulate Ca2+ influx in response to glutamate (7). Phosphorylation of NMDAR2B at Ser1303 has been shown to initiate Ca2+ overload during neuronal excitotoxicity and dephosphorylation at this site may confer neuroprotection (8).
