Anti-gamma-aminobutyric acid type A receptor subunit rho3 antibodies are used for the immunodetection of the protein encoded by the GABRR3 gene. In humans, the canonical protein has a reported length of 467 amino acid residues and a mass of 54.3 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 rho-3, GABA(C) receptor, gamma-aminobutyric acid (GABA) A receptor, rho 3, and gamma-aminobutyric acid receptor subunit rho-3. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
