Entrez ID	116444
Gene name	Glutamate ionotropic receptor NMDA type subunit 3B
Gene symbol	GRIN3B
Synonyms (NCBI Gene)	GluN3BNR3B
Chromosome	19
Chromosome location	19p13.3
Summary	The protein encoded by this gene is a subunit of an N-methyl-D-aspartate (NMDA) receptor. The encoded protein is found primarily in motor neurons, where it forms a heterotetramer with GRIN1 to create an excitatory glycine receptor. Variations in this gene

Protein name

Glutamate receptor ionotropic, NMDA 3B (GluN3B) (N-methyl-D-aspartate receptor subtype 3B) (NMDAR3B) (NR3B)

Protein function

Component of a non-conventional N-methyl-D-aspartate (NMDA) receptors (NMDARs) that function as heterotetrameric, ligand-gated cation channels with low calcium permeability and low voltage-dependent block by Mg(2+) (By similarity). Forms glutama
