Gene: GRIN1 (glutamate ionotropic receptor NMDA type subunit 1) Homo sapiens
Symbol: GRIN1
Name: glutamate ionotropic receptor NMDA type subunit 1
Description: Exhibits amino acid binding activity and ionotropic glutamate receptor activity. Contributes to calcium channel activity. Involved in several processes, including calcium ion transmembrane import into cytosol; response to ethanol; and response to glycine. Localizes to NMDA selective glutamate receptor complex and dendrite. Implicated in alcohol use disorder; autosomal dominant non-syndromic intellectual disability 8; and cerebral infarction. Biomarker of Alzheimer's disease and vascular dementia.
Type: protein-coding
RefSeq Status: REVIEWED
