Anti-gamma-aminobutyric acid (GABA) A receptor, rho 3 antibodies enable researchers to detect and measure the gamma-aminobutyric acid (GABA) A receptor, rho 3 antigen in biological samples. This target is a reported synonym of the GABRR3 gene, which encodes gamma-aminobutyric acid type A receptor subunit rho3. This protein is known to function in chemical synaptic transmission and signal transduction pathways, among other biological roles. The human version of gamma-aminobutyric acid (GABA) A receptor, rho 3 has a canonical amino acid length of 467 residues and a protein mass of 54.3 kilodaltons. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include gamma-aminobutyric acid receptor subunit rho-3, GABA(A) receptor subunit rho-3, and GABA(C) receptor.
