Anti-gamma-aminobutyric acid type A receptor subunit delta antibodies are used for the immunodetection of the protein encoded by the GABRD gene. In humans, the canonical protein has a reported length of 452 amino acid residues and a mass of 50.7 kDa. Its subcellular localization is in the cell membrane. A member of the Ligand-gated ion channel (TC 1.A.9) protein family, it is known to be involved with chemical synaptic transmission and signal transduction pathways. Post-translational modifications have been described, including glycosylation. The gene encoding this protein is implicated in Generalized epilepsy with febrile seizures plus. Other names for this target antigen include EJM7, GEFSP5, gamma-aminobutyric acid receptor subunit delta, GABA(A) receptor subunit delta, GABA(A) receptor, delta, and EIG10. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
