Anti-GRIK4 antibodies are used in the immunodetection of the protein glutamate ionotropic receptor kainate type subunit 4. In humans, the canonical protein has a reported length of 956 amino acid residues and a mass of 107.2 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in the caudate and hippocampus. A member of the Glutamate-gated ion channel (TC 1.A.10.1) protein family, GRIK4 is a known receptor for glutamate. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include GRIK, GluK4, GluK4-2, KA1, glutamate receptor ionotropic, kainate 4, and EAA1. GRIK4 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some GRIK4 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
