Anti-gamma-aminobutyric acid type A receptor subunit rho 2 antibodies are used for the immunodetection of the protein encoded by the GABRR2 gene. In humans, the canonical protein has a reported length of 465 amino acid residues and a mass of 54.2 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-C receptor, rho-2 subunit, gamma-aminobutyric acid (GABA) A receptor, rho 2, gamma-aminobutyric acid type A receptor rho2 subunit, and gamma-aminobutyric acid receptor subunit rho-2. Gene orthologs have been identified in the mouse, rat, bovine and chimpanzee species.
