Gene Gene information from NCBI Gene database.
Entrez ID 2904
Gene name Glutamate ionotropic receptor NMDA type subunit 2B
Gene symbol GRIN2B
Synonyms (NCBI Gene)
DEE27EIEE27GluN2BMRD6NMDAR2BNR2BNR3hNR3
Chromosome 12
Chromosome location 12p13.1
Summary This gene encodes a member of the N-methyl-D-aspartate (NMDA) receptor family within the ionotropic glutamate receptor superfamily. The encoded protein is a subunit of the NMDA receptor ion channel which acts as an agonist binding site for glutamate. The
