GRIN2D encodes the human gene, Glutamate receptor, ionotropic, N-methyl D-aspartate 2D. It may also be known as: Glutamate receptor ionotropic, NMDA 2D; GluN2D; EB11; Glutamate [NMDA] receptor subunit epsilon-4; N-methyl D-aspartate receptor subtype 2D; NMDAR2D; NR2D; N-methyl-d-aspartate receptor subunit 2D. The encoded protein has an amino acid length of 1336 and a mass of 143.8 kDa. GRIN2D is a member of the Glutamate-gated ion channel (TC 1.A.10.1) family, NR2D/GRIN2D subfamily. Homologs of this gene exist in other organisms, including: Mouse.
