Anti-GRIN3A antibodies are used in the immunodetection of the protein glutamate ionotropic receptor NMDA type subunit 3A. In humans, the canonical protein has a reported length of 1115 amino acid residues and a mass of 125.5 kDa. Its subcellular localization is in the cell membrane. A member of the Glutamate-gated ion channel (TC 1.A.10.1) protein family, it is known to be involved with the transport of ions and dendrite development. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include N-methyl-D-aspartate receptor subtype 3A, glutamate [NMDA] receptor subunit 3A, glutamate receptor, ionotropic, N-methyl-D-aspartate 3A, and glutamate receptor ionotropic, NMDA 3A.
