Predicted to enable NMDA glutamate receptor activity and transmitter-gated monoatomic ion channel activity involved in regulation of postsynaptic membrane potential. Predicted to be involved in excitatory postsynaptic potential; glutamatergic synaptic transmission; and long-term synaptic potentiation. Predicted to act upstream of or within monoatomic ion transmembrane transport. Predicted to be located in postsynaptic membrane. Predicted to be part of NMDA selective glutamate receptor complex. Predicted to be active in postsynaptic density membrane. Orthologous to human GRIN2C (glutamate ionotropic receptor NMDA type subunit 2C).
