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]

Function

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]

Clinical significance

Several genetic epidemiology studies have shown a strong association between several variants of the GRID1 gene and increased risk of developing schizophrenia.^[12][13]
