GRID1

Glutamate receptor delta-1 subunit also known as GluD1 or GluRδ1 is a protein that in humans is encoded by the "GRID1" gene.
Function.
This gene encodes a subunit of glutamate receptor ligand-gated ion channel. These channels mediate most of the fast excitatory synaptic transmission in the central nervous system and play key roles in synaptic plasticity.
Clinical significance.
Several genetic epidemiology studies have shown a strong association between several variants of the GRID1 gene and increased risk of developing schizophrenia.
