Summaries for GRID1 Gene

Entrez Gene Summary for GRID1 Gene

  • This gene encodes a subunit of glutamate receptor channels. These channels mediate most of the fast excitatory synaptic transmission in the central nervous system and play key roles in synaptic plasticity.[provided by RefSeq, Jan 2009]

GeneCards Summary for GRID1 Gene

GRID1 (Glutamate Receptor, Ionotropic, Delta 1) is a Protein Coding gene. Among its related pathways are Peptide ligand-binding receptors. GO annotations related to this gene include extracellular-glutamate-gated ion channel activity and ionotropic glutamate receptor activity. An important paralog of this gene is GRID2.

UniProtKB/Swiss-Prot for GRID1 Gene

  • Receptor for glutamate. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. The postsynaptic actions of Glu are mediated by a variety of receptors that are named according to their selective agonists
