The GRIA2 gene encodes for glutamate receptor 2 with an isoform flop of 883 amino acids, 98 kDA, isoform flip of 883 amino acids and 98 kDA, and an isoform 3 of 901 amino acids long and 100 kDA. Glutamate receptors function as a ligand-gated ion channel in the central nervous system and are the predominant excitatory neurotransmitter receptors in the brain. GRIA2 has been researched regarding its role in Alzheimer's disease, multiple sclerosis, motor neuron disease, epilepsy, anorexia, bioplar disorder, and neurodegeneration. GRIA2 is involved in the CREB pathway, intracellular calcium signaling, glutamic acid signaling, and calcium channels as well as interacts with genes NSF, GRIA3, DLG4, GRID2, and SDCBP.
