Anti-gamma-aminobutyric acid type A receptor rho 1 subunit antibodies are used in antigen-specific immunodetection in biological samples. The target gamma-aminobutyric acid type A receptor rho 1 subunit is a known alias name of the protein gamma-aminobutyric acid type A receptor subunit rho1, encoded by the GABRR1 gene in humans. This 479-amino acid residue protein is known to be involved in chemical synaptic transmission and signal transduction pathways, among other biological processes. It is localized to the cell membrane of the cell and features glycosylated post-translational modifications. In terms of tissue expression, it is reported to be highly expressed in the retina and in a lesser extent in the brain, lung and thymus.
