Model of NR2 Subunit.
Schematic of vertebrate NR2A or NR2B subunits. Note the long intracellular C-terminal domain and relative positioning of particular interacting proteins. PSD-95 is a scaffolding protein, while CaMKII and P13K are kinases that phosphorylate the NMDA receptor.
Schematic of invertebrate NR2. Note the significantly shorter intracellular C-terminus.
