GRID1 encodes the human gene, Glutamate receptor, ionotropic, delta 1. It may also be known as: Glutamate receptor ionotropic, delta-1; GluD1; GluR delta-1 subunit. The encoded protein has an amino acid length of 1009 and a mass of 112.1 kDa. Other isoforms may exist. GRID1 is a member of the Glutamate-gated ion channel (TC 1.A.10.1) family, GRID1 subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
