Anti-gamma-aminobutyric acid type A receptor rho 2 subunit antibodies are used in antigen-specific immunodetection in biological samples. The target gamma-aminobutyric acid type A receptor rho 2 subunit is a known alias name of the protein gamma-aminobutyric acid type A receptor subunit rho2, encoded by the GABRR2 gene in humans. This 465-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.
