Anti-gamma-aminobutyric acid type A receptor beta 2 subunit antibodies enable researchers to detect and measure the gamma-aminobutyric acid type A receptor beta 2 subunit antigen in biological samples. This target is a reported synonym of the GABRB2 gene, which encodes gamma-aminobutyric acid type A receptor subunit beta2. This protein is known to function in chemical synaptic transmission, among other biological roles. The human version of gamma-aminobutyric acid type A receptor beta 2 subunit has a canonical amino acid length of 512 residues and a protein mass of 59.2 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cytoplasmic vesicles and cell membrane of cells and notably expressed in the cerebellum. gamma-aminobutyric acid type A receptor beta 2 subunit is a member of the Ligand-gated ion channel (TC 1.A.9) protein family.
