NMDA receptors composed of NR1/NR2C exhibit a low conductance and reduced sensitivity to Mg(2+), compared with the more commonly studied NR2A- and NR2B-containing receptors. Despite these interesting features, very little is known about the regulation of NR2C function. Here we investigate the role of phosphorylation of NR2C in regulating NMDA receptor trafficking and ion channel properties. We identify a phosphorylation site, serine 1244 (Ser(1244)), near the extreme COOH terminus of NR2C, which is phosphorylated by both cAMP-dependent protein kinase and protein kinase C. This residue is located adjacent to the consensus PDZ ligand, a region that regulates protein-protein interactions and receptor trafficking in NR2A and NR2B. We show that Ser(1244) on NR2C is phosphorylated in vitro, in heterologous cells, and in neurons. Moreover, we demonstrate for the first time that NR2C interacts with the PSD-95 family of PDZ domain-containing proteins but that phosphorylation of Ser(1244) does not influence this PDZ interaction. Furthermore, Ser(1244) phosphorylation does not regulate surface expression of NR1/NR2C receptors. However, we find that this site does regulate the kinetics of the ion channel: a phosphomimetic mutation at Ser(1244) accelerates both the rise and decay of NMDA-evoked currents in excised patches from HEK-293 cells. Therefore, phosphorylation of Ser(1244) does not regulate trafficking but unexpectedly affects ion channel function, suggesting that phosphorylation of Ser(1244) on NR2C may be important in defining the functional properties of NMDA receptor-mediated currents in the cerebellum."xsd:string |
