Anti-gamma-aminobutyric acid type A receptor subunit theta antibodies are used for the immunodetection of the protein encoded by the GABRQ gene. In humans, the canonical protein has a reported length of 632 amino acid residues and a mass of 72 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. Other names for this target antigen include GABA(A) receptor subunit theta, gamma-aminobutyric acid (GABA) A receptor, theta, gamma-aminobutyric acid type A receptor theta subunit, and gamma-aminobutyric acid receptor subunit theta. Gene orthologs have been identified in the mouse, rat, bovine, chimpanzee and chicken species.
