Gene: GRIN2B (glutamate ionotropic receptor NMDA type subunit 2B) Homo sapiens
Symbol: GRIN2B
Name: glutamate ionotropic receptor NMDA type subunit 2B
CRRD ID: 731079
Description: Exhibits NMDA glutamate receptor activity; glutamate-gated calcium ion channel activity; and glycine binding activity. Involved in calcium ion transmembrane import into cytosol and response to ethanol. Localizes to NMDA selective glutamate receptor complex. Implicated in several diseases, including alcohol use disorder; autosomal dominant non-syndromic intellectual disability 6; bipolar disorder; early infantile epileptic encephalopathy 27; and neurodegenerative disease (multiple). Biomarker of Alzheimer's disease; temporal lobe epilepsy; and vascular dementia.
Type: protein-coding
RefSeq Status: REVIEWED
