Anti-gamma-aminobutyric acid type A receptor subunit alpha4 antibodies are used for the immunodetection of the protein encoded by the GABRA4 gene. In humans, the canonical protein has a reported length of 554 amino acid residues and a mass of 61.6 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 signal transduction pathways. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include GABA(A) receptor, alpha 4, gamma-aminobutyric acid (GABA) A receptor, alpha 4, gamma-aminobutyric acid A receptor alpha 4, and gamma-aminobutyric acid receptor subunit alpha-4. Gene orthologs have been identified in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species.
