Anti-gamma-aminobutyric acid type A receptor beta 1 subunit antibodies are used in antigen-specific immunodetection in biological samples. The target gamma-aminobutyric acid type A receptor beta 1 subunit is a known alias name of the protein gamma-aminobutyric acid type A receptor subunit beta1, encoded by the GABRB1 gene in humans. This 474-amino acid residue protein is a known component of the heteropentameric receptor for GABA, the major inhibitory neurotransmitter in the vertebrate brain. It is localized to the cell membrane of the cell and features glycosylated post-translational modifications.
