Glutamate receptor delta-1 subunit also known as GluD1 or GluRδ1 is a transmembrane protein[5][6] (1009 aa) encoded by the GRID1 gene.[7][8] A C-terminal GluD1 splicing isoform (896 aa) has been described based on mRNA analysis.[9]

This gene encodes a subunit of glutamate receptor ligand-gated ion channel. Most of these channels mediate fast excitatory synaptic transmission in the central nervous system. GluD1 is expressed in the central nervous system[10] and is important in synaptic plasticity.[7][11]
Several genetic epidemiology studies have shown a strong association between several variants of the GRID1 gene and increased risk of developing schizophrenia.[12][13]
